So I was just re-watching some videos and reading interview to find it. I haven't been able to find it yet. However there is some information on public dungeons in the tamriel foundry coverage.
"Public dungeons are really exciting because a public dungeon operates almost exactly like an overworld zone. It’s just slightly harder than the overworld zone to encourage people to team up" - http://tamrielfoundry.com/2012/10/interview-matt-paul/
"Also, there are all the public dungeons; we have a lot of public dungeons in Cyrodiil as well." - http://tamrielfoundry.com/2012/10/interview-brian-wheeler/
"This dungeon is intended to challenge players between levels 5 and 7, I had achieved level 9 by the time I reached it, so was able to handle its challenges without assistance." - http://tamrielfoundry.com/2012/10/gameplay-impressions/
I guess you have already seen my post #33 now.
I just looked up the source (Episode 43; 1:07:37 - and on) for saying there was a cooldown, it may not be all skills and the most limiting thing is still going to be your Stamina and Magicka. He also goes over some of the Templar skills in more detail. If you haven't heard that podcast before, give the whole thing a listen, it's packed full of information. Maybe also listen to the episode before that, it has some interviews and stuff.

It looks like you have edited that part a bit now anyway. There is a bit of information in the podcast I linked above about weapons.
Another good source on the subject is a preview at mpogd. I would love the know what that "and Rune" part is talking about, runes are weapons of some type?
"Whether the full list had been incorporated or yet I'm not quite sure, but so far players can use a Two-Hander, 1-Hand and Shield, Dual Wield, Bow, Fire Staff, Ice Staff, Lightning Staff, Heal Staff, or 1-Hand and Rune. Much like how the game handles abilities and how the single-player stresses becoming more proficient with weapons the longer you use them, the longer you use a single weapon the more powerful you'll get with it. While playing my Dragonknight, I chose to go the 1-Hand and Shield route, which features a leveling system such as this:
- Stalwart (passive) - reduce stamina cost of blocking 80
- Crippling Strike - deals 18 physical damage snare for 20% for 5 seconds and stacks up to three times
- Passive Aggressive (passive) - reduce stamina cost of blocking by 20%
There are a total of eight ranks by which you can increase your character's proficiency"

That helps alot

"Yes, there will be an Online Trading Post, where you can put items up for sale. Though, the extent of this has not been stated whether it is faction locked or a Global Market, where you can sell through all 3 different factions."
I think the trading is only between your fraction. In the pc gamer interview they talk about how Maria could craft something and put it up for sale to other fraction members( see 5:55 in video). In the context of that video it wouldn't make any sense if any fraction could buy the stuff put up by the other fractions. Just to note that is also the video they talk about summoning a pet with a ultimate ability(10:20).
