If they just show LBP, KZ2, R2, GoW3, or GT5 stuff, ... that's pretty much what has been expected.
Who cares. The only third-party 360 exclusive even remotely approaching FFXIII is Gears2. So they will hardly one-up Microsoft on this front.
But this is not about exceeding expectations but about showing great games and if they have an awesome God of War3 trailer and a Team Ico game they will show more games I want to play than Microsoft and this is the only important factor. Because of this I also do not understand all the Sony is dead bruhaha on this site . Microsoft still doesn't have any killer exclusives. Fable2 looked ok but not spectacular in any way, Gears2 has a great movie-feeling but is Gears1-redone, Lips is a Singstar rip-off.
I am not even saying that the current lineup of SONY is much better. Resistance2 is cool but its not as polished as Gears2, Killzone2 looks at least as good but I don't know about gameplay, LittleBigPlanet has huge potential but will the gameplay be fun?, Gran Turismo will be the best racing game this gen but only 2009, Socom and Motorstorm are nice but not huge, but some great gameplay vids of God of War3, Shadow of the Colossus PS3 or Uncharted2 and this is different.
I do understand that 360 owners now have a big reason less to also buy a PS3. But this is a problem mostly confined to this forum, most people will not own both consoles.
