GT5 for many many months. Looking forward to the re-mastered Shadow of the Colossus and the new Last Guardian coming out next year. Maybe CoD, but MW2 seriously ate up my life this past year lol. Maybe FIFA.
You guys don't forget about Kollection HD, Rachet N Clank in 4 in One Pack, Persia of Sand Collection HD, Ico and Shadows of Colossus collection in 2011, too. Twisted Metal would be my first priority to buy, then Dead Space 2 or Homefront would be my second priority!
