They probably will do it, as they were hiring a PC transfer person or helper or whatever. I read it somewhere, that probably is a big hint that they are gonna release it for PC, just probably sometime after the console versions are released.
I hear you. I wouldn't be even able to run it at all, even with low settings. :( But if I did get it on the PC (if it comes out for it) and I was actually able to run it, I wouldn't be able to help myself from downloading mods, so to stop myself from doing so, I pre-ordered it for Xbox 360 instead. And, like I said my computer would never be able to run it.
