Assassin's Creed and Rockband Unplugged will be critical for 2009.
LittleBigPlanet will also have some success, though it isn't a big franchise like the above. Don't think Motorstorm will help much, but I'll be picking it up if it's anything like the other two.
Crucially though, Sony should have cut the PSP's price to $99, rather than the PS2's. I think that is their biggest mistake of 2009 so far.
