I expect to see in game footage with no lag issues! lol.
On a serious note: a video of current content leading into a CGI for 2.0 and then some short clips of areas fighting etc flicking around, then a fade to black, final fantasy 2.0 new logo fading onto screen, then a sudden flash of Ultima end.
I think if they show this at the Sony stand they're gonna show things that relate it to old final fantasies such as ultima behemoth etc. this will spark new interest in the series fan base. They also might have a playable demo that Yoshi P or someone from SE will play through showing us some actual in game play, either on stage or at a computer with someone interviewing them. announcement of new XIV 2.0 website and then maybe some additional info here on the Lodestone for the oh so loyal XIV fans!
