No, FFXIII will not be downgraded like GTAIV.

I dont know why people want to pretend to live in a bubble like they don't know MS plays "dirty/different". When a company is accused of unagreeable practices they REFUTE it in the press. Sony completely REFUTED the idea of them moneyhatting as MS does. Instead of MS denying it they simply dodge the question. Companies are not allowed to lie to the public, only bend the truth and stay quiet.

There has been a recent upsergence in Sony to point out the fact that MS is Moneyhatting and that they don't(or at least not to their extent). If this was untrue I have no doubt in my mind MS would sue Sony for slander.
