It really does depend on how well the console versions sell, since the PC sales will be complete shit due to Volition's hideously retarded attempt to shove it on Epic. That alone would kill a lot of sales just due to being on a far smaller platform.
Since even the paid shills are calling it shit, my guess is it'll sell like shit though. Especially since the retarded consoomer base for the IP is a lot smaller than they think it is. I feel like they are overselling their pre-order numbers though, likely as a way to cope. Especially since odds aren't too bad for refunds to ensue due to how actually buggy the game is.
