So far:
Resident Evil 6 (hell yeah!)
Borderlands 2 - i believe they are trying to make an end of year release but at this rate probably early 2013
The Last Guardian - Heard rumors it will be out this year; looking forward to it since its been done by a a pure Japanese Patriot down at team ICO
http://en.wikipedia.org/wiki/The_Last_Guardian - sony complained that it was taking too long, so he basically gave them the middle finger and said he will take as long as he needs and said that this is the last game for them i.e. this should be epic.
These will will be definitive buys for me no exception
Im sure i missed something, will post it up again
