This reminds me of what we were told around the launch of Windows Vista. We would get Games Explorer to go with Windows Explorer and Internet Explorer. The new Windows Experience Index meant even techno-illiterate grandmothers could read system requirements. DX10 was so advanced it couldn't possibly be backported to Windows XP.
The new Games for Windows certification system meant PC games would be as bug free and user friendly as console games, and Microsoft would ensure GfW games would get plenty of prime shelf space in game stores. If PC gamers would just pay their GfW Live subscription they could even play Shadowrun with those cool guys at Xbox Live.
And to really show off their support for PC gaming, Microsoft shut down Ensemble Studios and Microsoft Flight Simulator. I don't think Microsoft has published a single PC games since the two Vista "Launch Titles": Shadowrun and Halo 2.
If this new push for PC gaming is as good as the last I should probably figure out how to update my graphics drivers in Linux.
