Not a chance.
You've got some serious PC titles with more and more information.
WoW expansion
Diablo III
Etc
Sony has a ridiculous lineup of upcoming titles.
Killzone 3
Infamous 2
(Possible Uncharted 3 reveal)
Socom 4
PSMove
Gran Turismo 5
Last Guardian
Agent
Final Fantasy XIV / Versus
etc.
Microsoft always pulls some serious stuff out of their sleeves.
- The highly hyped and anticipated Project Natal reveals...
- A new full-fledged Halo title
- Gear of War 3?
- Other big surprises?
Nintendo while looking a tad underwhelming at the moment still has some possible aces up it's sleeves.
- New Zelda reveal?
- More details/info on 3DDS
- And Im sure several other games (that haven't been announced) might make an appearance as well.
I don't think there is a chance that this E3 isn't awesome. Over hyped? It could be. Disappointing? No way.
