Probably - CS and a few in game trailers.

What i'd like:
Overview of combat :
Which would include colision/physics (blocking a mob with your body to keep it away from the mages ect)
New animations/attacks/spells.
Body part targeting on large mobs to inflict status effect style injury.

Overview of new UI+info on customisation

A good look some of the new maps.
As i'm hoping they are still realistic, relatively huge but with a lot more fantasy dotted about.
A good look at one of the towns too see what's if much has changed.

An finally something about summoners, group crating and to actually see some life in the npcs, camps and hamlets so they look lived in populated and not just filed with static un-animated content.
Oww and aggressive mobs attacking weak ones, imperial attacks being fought off by the camp/town guards,...

Hmm... nvm lol..
i'll go back to wishful thinking..
