Sure. MS want to win E3, so they have all of this holidays titles left to announce, as well as others further out.
Sony's concentrating on PSP for E3, hence why they've announced all their PS3 games for the next 12 months, but keep teasing "75% of the 2009 PSP lineup still a secret".
Obviously a console is more interesting than a handheld and Nintendo never impresses, so it's looking easy on paper.
Not much interested in the graphics debate, every supposed mega-PS3 exclusive that was supposed to set an impossible graphics bar has been slain within months, unsurprisingly by non-exclusives as well, looking over the first 2 years of the console, there isn't a PS3 exclusive's graphics you can't get on Xbox either the same or better.
Now the platform has plateaued with it's 4th gen games looking far too much like their 2nd gen ones, Uncharted 2 looks the same as Uncharted 2, same with Motorstorm, Resistance, Ratchet and it's not like MAG or Heavy Rain are pushing the boundaries either, quite hilarious really given many of them said they were only using 30% of the PS3s power, then 2 years later show up with a game that looks the same.
