I recently read an article that Microsoft wanted to get more gamers back to Windows. That’s why the next Windows should pay a lot of attention to gamers. So PC is MS to. I don't know if Nvidia also had their hands in it. I know they did with Crysis 1 and they are already using Crysis 2 on their sites to promote their cards, so it's likely there also investing in Crysis 2. That makes 2 companies (MS and Nvidia) that want to have a good PC-version. Of course for now MS will have its main focus on the Xbox but still. Maybe it's something like. Make it a marvel on the PC but before release only show Xbox stuff.
Hahahaha! Microsoft has been claiming PC gaming support since Windows 95. Other than DirectX (and even that was garbage until DirectX 9), Microsoft has only done more harm to PC gaming than good.
In fact, Microsoft (along with Nvidia), recently left the PC Gaming Alliance: http://www.gamereactor.eu/news/6542/Microsoft+leaves+PCGA/?cat=news
Microsoft just has a lot more interest in the Xbox 360 since they can screw more money out of people there. Microsoft tried to screw PC gamers a while back with Vista exclusivity and trying to make them pay for Live with Games for Windows Live. Microsoft claimed to be supporting PC gaming back then and yet all they did was launch a label (Games for Windows) and release a few shoddy ports of old games (Halo 2 and Gears of War, a year or more after they were released on the Xbox/Xbox 360 and they even slapped Vista exclusivity on Halo 2 even though it was originally on the Xbox, a DirectX 8 machine).
Microsoft can lick my asscrack. They're only in it to screw over people and force them to pay for things that should be free.
