The new Ratchet & Clank, and Bioshock are the two I've got on the go at the moment. Got Bioshock 2 to get to after that, plus Silent Hill Homecoming which I rented and played a bit of last year, but bought cheap a few weeks ago and haven't touched yet. Also got Dead Space which again, I rented and completed last year, but got it for Xmas just gone. Heavy Rain should be on its way but seems to have become lost in the post, and Bad Company 2 should get here tomorrow.
As for PC games...nah, I won't even go there.
That's really bad, usually as far as the PS3 is concerned I've got one game on the go at any time, occasionally two perhaps.
