PC gamers staying classy, I see.
There's not a lot I can say, though, other than repeat that XCOM:EW was one of my favourite games of last gen, and it completely sucks I won't be enjoying the sequel. 'Sticking to what you know' is fair enough, I suppose, but it's also deeply unambitious and slightly disingenuous when considering the platforms that EU/EW appeared on, successfully. And, as others have stated, the mention of graphical fidelity seems a bit ridiculous - on an XCOM? Really? Pft, don't think so, unless the end result is some kind of benchmark for the [sub]genre.
If I ever do ever get a PC that can run new games (highly unlikely, in the near future), I hope they at least implement excellent controller support, because XCOM:EW worked so damn well with a pad.
