Dead space 2 because of the move thing.
L.A.Noire project started with some investment from Sony;..I guess they got their money back but they didn't forgot sony's investment?
They wanted to create an exclusive mortal kombat character for X360 aswell (read it here on the forums) but in the end it didn't happen for a reason..
Portal 2, Maybe because of valve's past they wanted to do something extra for Sony?
