I've read the changelog of the next patch and I find the list of corrections really small compared to the amount of bugs already reported, especially about the quests.
I will not list all bugs here, but I ask the question to the developers : are you aware about this site ?

http://www.uesp.net
http://www.uesp.net/wiki/Skyrim:Quests

99% of the bugs are reported here, with generaly a lot of details to help fixing them.
Everything is here, under "Notes" & "Bugs"...

Hope you will take this topic in consideration, we all want the most perfect game possible...

I'm on that site all the time and in many cases because of a bug. It's a gold mine of information.

Once the creation kit is out, we'll see a lot of quests/gameplay/textures/etc bugs solved I guess, as always with Elder's Scroll

You want all bugs fixed and you want regular updates. This is somewhat contradictory.

1.4 will not be the last update - I'm sure more fixes will be provided in future updates as Bethesda works through the bugs. These things take time.
