Must say that i was positively surprised by Sony's conference. I only have a PS3 so far and judging from the E3 prehype, i thought MS would crush Sony with big name exclusives and such. And while not everything was that interesting in the Sony conference (i'm not really interested in psp, motion control and such), they had a decent line up of nice games, which is in the end, the most important aspect for a games console. It's a pity that so much of the stuff was leaked though. Imagine for example that Ico trailer without anyone seeing it before the show, it would have made an incredible impact. The whole conference would have made a bigger impact.
There's definately fun stuff for 2009 and 2010 on PS3. Lot's of nice PSN releases (trine, fat princess, pixeljunk shooter and others) and(t expansions (motorstorm, wipeout) and a good selection of exclusive and multiplatform games. I just hope that the multiplatform games will have good ports to the PS3, which hasn't always been the case in the past.
