The important thing is that XBOX has atleast a very strong market in US.. and then XBOX is having very strong showing till now..
So when Sony realised that they will be yr late in launching PS3, they must had thought about how it will take the compitition and they might have calculated how much time it will taken them to over take the competition... But after yr and a half they r still third and they will remain so for some foreseeable future.
So definitely their plan, if there was any, is not working. Sony is loosing exclusives and not getting any more.. so definitely its not helping them...
So they have much much more to worry... MS is gaining Sony's game and i think they will be pretty happy... plus so far they have kept their exclusives to them too.
