Capcom said before that the reason demos and other things like DLC etc are occasionally delayed for PS3 users is because of quality assurance. Sony has several different regions and each one has its own panel or whatever that games have to go through. They also mentioned that it is quite lengthy to go through Sony's QA as they're very stringent.
Now, I personally believe money hats go around from ALL camps and if you look closely you'll see some obvious ones at that. I do not believe Microsoft money hated the demo in NA, Japan I have no idea as that was released a while back right?
Anyway. This is highly unlikely to be a case of "teh money hat", besides. It's just a demo and it'll be available for all on the 2nd and KZ2 on the 5th.
