Sonic Generations version for Steam leaked

The PC-version of Sonic Generations seem to have been leaked: Not only did it appear for a short time in a blog post by Sega, but it also appears in the internal listing of all games for the Steam service. There also seems to be a bundle coming to Steam that includes all previously on Steam released Sonic games with Sonic Generations. These information have been partially uncovered by NeoGAF users.
