FF Versus going multi-plat is the obvious announcement, the MEGATON will be Sony fanboys throwing themselves off buildings due to Kojima's next game being multi-plat. Assumptions are a terrible thing, same thing happened with FFXIII and we all know how that turned out.
GT5 announced, gameplay shown + release date would top anything MS could do. That one announcement which is long overdue would simply take care of anything MS have to offer, simple as that. All Sony need to do at E3 is show gameplay and actually give release dates for already announced games, end of that.
MS have the most work to do, Forza 3 should be announced but as I said GT5 would topple that with ease. Oh yes Halo ODST, cannot wait to see that one in action. :O Nintendo can have a pie eating contest during their conference and it will not matter at all, Nintendo is a monster.
