It will boost sales for sure. Japan will go nuts with this one and it is a big franchise in the US, i'm sure EMEA will love it too. This may be the game that has some 360 players on board.
I must say - the PS3 is starting to get some really good exclusives - Ratchet and Clank, Uncharted, Haze, UTIII (for a few months), RFOM, MGS4...
And the new bowling game for $9.99 is cool - the entire family came finally join in - rather then watch me play COD4 all night!
