imo 2012 will be the biggest year for PS3. i'm not sure if they will have Uncharted 3 or not however, they might decide that they want to release it for the launch of the PS4, and Naughty Dog might be working on something else at the moment, no idea tbh.
but i think after the team Ico HD release comes out they'll have a few supprises lined up for next year. and i think you forgot Mass Effect (Defect 2) and 3, i know that its multiplatform, but its still going to be a high profile release for the PS3 i think.
