Cliff B said it was exclusive, and that they arent even thinking about the PC right now. Allard said that if demand is there, than yeah it would make sense to port it for the PC. What will happen? Maybe you will get a port of it, but EPic wont start working on it till the Xbox 360 version has shipped, and maybe it wont even be EPIC doing it. And you will gget your port 1 year maybe more later.
The game will be marketed as Xbox 360 only, and maybe after a few months they will officially announce the PC port, but hey, JAde Empire was also supposed to make its way to the PC, and we still havent heard crap about it.
