Who really knows? I mean there are tons of multiplatform games being delayed for the PS3 and not the 360 so in my opinion I'd say the odds are that it is the PS3 holding things up. Honestly can you think of any multiplatform games that have been released so far that came out on the PS3 first and weren't timed exclusives bought by Sony?

I'm looking at the Wikipedia article (which may or may not be correct) but it says that game was originally a PS3 exclusive in Japan but had a simultaneous PS3/360 release in North America.
