GameSpot has an article with details on integrated voice chat, the troll outdoor dungeon instance Zul'Aman, and guild banks.

Looks like it'll be similar to Zul'Gurub. I've always liked the outdoor feel to it so I think I'll enjoy Zul'Aman.

The voice chat looks promising but I don't think people should count Ventrilo as obsolete (to the WoW community) though. Personally, I'm not sure how I'll handle the voice chat.

Guild banks. Seems like a good idea but I definitely am not the only one who thinks there is still chance for abuse in the system. Probably going to have to wait on a few more details before I think it's a good change.
