Ugh, there's no point in any of this. Even if it's just a timed exclusive, Konami would be contractually obligated to make no mention of the port until after the first version is released. We won't know what is going to happen until the PS3 version is already out. So everyone is just going to have to be patient.
My End of 2008 Hardware Predictions (console only):
Wii : 50 million
360: 28 million
PS3: 24 million
These predictions were made on January 3rd and won't be revised
