Well IMO the obvious is they will hype to the max games to be released 08' : LBP, KZ2, R2, Motorstorm Pacifica, Tekken 6, Naruto Ultimate Ninja Storm, Socom Confrontation.
Then they will reveal secret games that will make it late 08 early 09 : possibly Heavy Rain and/or Infamous
And trailers for 09' upcomming games : FFXIII, FF vs XIII, GoW 3, Team Ico new game, Uncharted 2, Twisted Metal, Eight Days, and more... way enough to make PS3 lineup stand out.
Then they might also announce Home to be out the next day after E3, and their new video on demand service for the US.
