I think it's a case of some section of the PC crowd who are simply dying for it! That's why they're editing it back.
It's actually quite disturbing. Cos when I saw the page at first I was really excited. Now it let me down quite badly! Had I knew in the first place that there was no PC version coming. This wouldn't have been so painful.
To be perfectly honest those shopping sites actually deserve a slap for making photoshopped PC covers with the Games for Windows Live banner! Just brainwashing PC Gamers into believing something that isn't true.
With Origin in mind, any PC Gamer with a bit of intelligence would realize that no EA game that comes on Origin would utilize Games for Windows Live! Absolutely no EA game on Origin! Origin was made for a reason in the first place to activate your serial number, to have friends chatting, etc. GFWL wouldn't make sense, because GFWL in itself is like Origin that would also ask for a Product Code, also have the same friends chat system. GFWL would only have made sense if Origin didn't exist in the first place.
The only cover that I would believe in, is the PC DVD in the corner of the cover. Like for instance in the FIFA 13 PC cover, there is no Games for Windows Live banner. It only has PC DVD in the corner of the cover. Now that is genuine!
