If people bothered to read and watch the interviews Todd has made throughout April, you would know that it will NOT be a port. It is being made with the PC in mind, and then will be scaled down for the consoles.
Yeah, that's why the PC version is getting DX11 goodies like tesselation, will use CPU-crunching advanced AI, will have memory-intensive features like open cities, and.. oh wait.
Sorry, the game is being developed for the lowest common denominator, and while the PC might get a couple goodies (higher res textures, a different UI), it's hardly being developed for the PC and scaled down on the consoles later.
