The 360 version already has noticeable limited graphics capability than the PS3 version.
we all knew that before the game had come out, the xbox is an inferior platform, how it's still competing with the PS3 as a Hi-Def gaming rig is only because people still aren't ready to shell out for a PS3 but they should, seeing how microsoft nickel and dime you for pretty much everything that comes as standard with a PS3
sorry for getting slightly off topic,
OK 2 points.
1) guys forgive me if I'm wrong, but clearly from the tone of these posts you are being a tad fanboi-ish here.
360 & PS3 hardware are pretty much the same. To say the 360 is weaker than the PS3 because FFXIII was the poorer port on the 360, is like saying Bayonetta proves the PS3 is weaker than 360 because it was much poorer.
Crap ports happen on either system.
Time to get over it and lose the attitude.
Your patronage to BRAND doesn't give you access to an exclusive club, it does not win you points in the afterlife and neither does it prove anything about the size of your manhood.
In fact being so 'brand loyal' is bad for the industry as it leads to companies becoming complacent about the consumer (as it assumes that the silly consumer will rush out and buy anything @ any price as longs as BRAND stick their logo on the front and exalt the virtues of it over competitors, regardless of whether those exalted virtues are legitimate or not), and what actually happens is that we see the quality and choice suffers overall.
So please less of the FanBoi stuff. It's getting really old right now.

This rumor if true, is simply economics. Ask yourself this question ? Am I willing to pay $100 for an insomniac or any other 'exclusive' game ? Developers & publishers can no longer take major gambles 'exclusively' as games development reached movie like budgets. For every one or two game that are successful for a publisher, there are 10-20 that fail at retail. When were talking $20,000,000 (or $40,000,000 in FFXIII's case) to make a game then it makes perfect business sense to make the game available on as many platforms as possible.
Sony & Microsoft are clearly unwilling to pay the extra $$$ development budgets of studios to off-set the reduced revenue from wider sales for an exclusive title.
It started with 'timed exclusives' disappearing. Now we have exclusive DLC that ends up being 'timed' too. Is it really any surprise in 2010 that a non first party company looks set to announce it is developing for the wider market. Not at all.
