I think its short-sighted to look at the games announced during the PS Meeting, and extrapolate that out, and come to the conclusion that Sony isn't going to deliver the games. New games franchises, returning franchises, indies, etc. That's what the PS3 was all about. The nature of the meeting wasn't to show us everything. We won't see everything at E3.
Moreover, we don't really even know how the game revealed play out. Say what you will about their marketing during this current generation, question their software sales figures, but no one has delivered has delivered as many games and as much diversity as Sony. I can't speak for anybody's tastes of course, but I think Sony's easily offered more games for quote unquote hardcore gamers. And while you've had your UnCharteds, Killzones, and God of Wars...you've had plenty of other games that tried something new and/or were wholly new IP.
I expect UnCharted to return, God of War eventually, LBP to return on top of Killzone and Infamous...but I think everything else is spanking new. The returning franchises are there to pull in fans, and get devs familiar with the hardware during the transition. Don't sleep on Sony in the games dept.
