Well I called it in one of my first videtorials. It would be REALLY stupid for Konami to spend all this money on the game and only release it on PS3. To increase sales of the game it only makes sense to go cross platform. The key here is game sales, not system loyalty.
[Edit] I noticed some traffic coming here today and decided to go back and read the original article at Destructoid. It seems that they got a lot of heat from it and edited it for internet Mattlockery. Ron Workman is a genius!
