The blame here sits mainly with Namco.
They put it out on 360 first, perhaps with incentives by MS, perhaps not, but in the end it was their choice.
They decided to bring it to PS3, probably seeking additional sales, and hit the Sony policy that late ports of previously exclusive games had to have new content. This is a fair enough policy IMHO to counter effect of timed exclusives.
In the end the key decision that caused this rests with Namco, not Sony or MS.
Try to be reasonable... its easier than you think...
