You can tell by your characters breathing. When they've been swimming too long, they start to choke.

Fletching arrows, as mentioned before.

I'd love to see that put in, it would be so helpful.

I want my waters to have textures and the lighting engine to stop having a seizure.

A new weapon type

More in the way of character development (like attributes or fallout's "special")

New skill trees

For the love of Talos it would be great if followers etc. didn't say the same thing all the time. Lydia is killing me with "I am sworn to carry your burdens."
How about adding a few extra responses that they choose from?

• "Sure, what would you like to trade?"
  
• "My feet are killing me from these cheap boots you gave me, but I'll carry something else for you."
  
• "No problem, Thane."
  
• "Do I look like a pack mule? Just kidding!"
  
• "Not the Daedric armor! Anything but that!"

Think im gona take a nice long break from skyrim and then jump head long into the DLC when it comes out.

As an update to this, I now have to add that they should fix hawk bodies (and any other bodies), so that they get cleaned up/removed. As I mentioned in http://www.gamesas.com/topic/1373763-hawk-dead-bodies-dont-disappear-bug/, the hawks' bodies won't go away for me. [360]

1. Fix the Mask on the Dark Brotherhood Shrouded Cowl for Males Nords,.......etc

2. Fix the Headmans Axe where we can upgrade it.

3. Fix the bug while being a Vampire and wearing the Thieves guild hood where you do not go bald.

Per-pixel shadow shader.

A backpack or somethong like that cause I could carry 500kg of stuff including about 3 swords 2 bows and a handful of daggers IN A LOINCLOTH!

I agree.
Also the nirnroot bug.

I still suggest they just make a hardcoe mode where everything in a fantasy game is "realistic" for all the players who want to live a real life ...in a video game

^ What they said ^

Craftable staves (stick in smithing, finish in enchanting)
Craftable scrolls (enchanting)
Meltdown (smiting)
Craftable arrows (smithing)
Craftable herb bandages (restore health - alchemy)

Horses for followers

Scaling illusion spells
Cure spells (no vampirism)
Cure bandages in alchemy
Spell failiure

A fix for the spell absorb-conjuration bug(this really annoys mages using alteration and conjuration because of the astronach perk)
Unenchanted variants of existing robes, master-novice(I like the Adept robes) thalmor ect.(and similar treatment for the matching hoods)
Destruction magic balance
Steel Plate armor moved to the proper side of the smithing tree

Scaling Illusion spells? Perks make them effect practically any level enemy. Destruction however, is what needs proper scaling. Illusion is perfectly fine.

Vampires not attacking me unprovoked when I'm a vampire.
BUG FIXES.
Lower the [censored] killcam rate.

And... I dunno. Not much more I could ask for that could be covered with a patch.

A fix for the Boots and Gauntlets of the Old Gods so that everytime i load the game they dont magically morph into hand and foot rags that let me see through my own flesh

Fix leather and iron smithing so that they can be leveled like all other materials !!! Pretty please!!

Why this important thing was left out of the game baffles me. After all, Oblivion had one, as did Fallout 3 and New Vegas. Fortunately, I have been stockpiling Philters of Waterbreathing in the event that I have to be underwater for a long time in a quest (haven't had to yet)

Yes, but starting to choke when you're more than halfway to your goal isn't much help, is it? That's why you need a meter, so you know to find an air pocket, or know you need to head to the surface BEFORE you drown.

Being able to kill my noisy, stinking, ugly and neurotic muscle twitching barwife!

Since I play on Xbox and since I guess you couldn't really ask for too complicated things from a patch, I want this (besides bug-fixes) for 1.6:

1. Being able to give your spouse gifts (my character is married to Sylgja, and the fact that there is no legit way to replace her dirty mining clothes and pickax is starting to annoy me).

2. I want a quest that allows me to destroy the Dark Brotherhood even after the quest "With Friends Like These" have started. I (and many of those I have asked) thought that Astrid was one of those invincible characters, so I never tried to kill her, which I now regret deeply. I want an other chance to destroy the Dark Brotherhood.

3. I want a quest that allows me to destroy the Thieves Guild, even if you have done their dirty-work or even joined them.

4. I want to be able to choose the guild related homes / guild base to be a possible home for you AND your spouse.

5. I want to be able to choose which housecarl that should live in which house. I also want to be able to have many housecarls in one house.

6. I want to be able to rebuild Whiterun and Solitude after the sieges.

Body / ash pile / weapon cleanup a la 'Possessive Corpses'.

Consistent 'dungeon' repopulation. I know that some are not set to, but for me, Valtheim Towers and the Wreck of the Winter War, for example, do not repopulate. And those are only a couple examples. The loot respawns, but the enemies do not. Mods to decrease the spawning interval do not work, and I've tried sleeping for 90 days in different cells - no workie. It's like they're permanently empty for some reason, along with many other locations.

Allow PC to remove quests if they choose to (and co-jointly, untag related items as 'quest items'). And to be safe, implement a warning... like, "Are you sure you want to remove this quest? This action cannot be undone."

Spears (w/ noticeable reach benefit), Flails (w/ noticeable negation of blocking benefits for victim), and...

The announcement of the Dovahkiin Customizable Armor Shop. An online service that allows you to choose from several dozen unique pieces of armor, allow for color choices for each piece, and textural variations and decals to further complete the custom look. Once you've created your custom set of armor, you can review the set and it will be available to download for free or a small fee.

hm, battlefield 3 is still getting patches and updates and yet they have already released an expansion pack and other dlc lol

that game is bugged still
