Well damn that's a bold bet Aussie haha.
PS3:
Twisted Metal
Killzone 3
InFamous 2
Little Big Planet 2
Resistance 3
Uncharted 3: Drake's Deception
Ratchet and Clank: All 4 One
MotorStorm: Apocalypse
Socom 4
The Last Guardian (doubt it will get pushed back but there is still a vague Q4 2011 release date)
Sorcery
MLB: The Show 2011
Shadow of the Colossus/ICO collection
Those aren't shovelware either those are the already announced likely above 80 meta games. And like I said they will probably announce more come E3.
360:
Gears of War 3
Kingdoms
Star Wars Kinect
Halo: CE remake (a longshot but who knows)
0.o I'm sure I missed alot on the 360 side so please feel free to correct me.
Wii:
Legend of Zelda: Skyward Sword
Pokemon B/W Box (or something in that vein)
And I know I'm missing alot here too so please fill them in.
My point being I don't think even wih E3 around the corner that MS or Nintendo can match the sheer number of PS3 exclusives coming out this year. And They don't have to, this is obviously going to be a good year for all but I don't think it's a safe bet considering what we already know.
