The first video gives a little more information about monsters you'll face including new demon from Coldharbour.

The second didn't seem to tell me anymore than I already knew but it reiterates some facts people may not be aware of for PVP.

On the side. I'm a bit disspointed with the information that has came out of E3 about TESO so far, apart from it coming to consoles the general lot of other information hasn't been all that great. Interviews just asking questions from the public - people who clearly know nothing about the game and the Gamespot interview showed that.
