I don't think Sony cares about beating the XBox360. I think they care about finally making money on the PS3. I'd rather there be a PS4, than have them take a huge hit on the PS3, take the lead, and lose so much money it forces them out of the hardware business.
But I am a little disappointed with PS3 sales and a lot of the negativity that seems to surround everything PS3 related (with exception to some rabid Sony fanboys).
