Doing a port from the PS3 to the 360 can be hideously easy, and Cross Edge isn't exactly a technical marvel. There's a fair chance it all runs on the PPU, and all the port will need is a rebuilt DevStudio project, and a reworking of the (likely simplistic) GPU shaders it uses, along with a few low level SDK items, like the input system, and some assorted OS stuff.
Not every game taxes the PS3 (or 360), and actually requires serious effort, and expense, to port. Unless you're Activision/Blizzard, I mean.
