Bandai Namco makes about two-thirds of the gaming friends I have giddy with joy:

We are very excited to announce that next month it will be possible for players to migrate their Dark Souls: Prepare to Die games, saves and achievements from the Games for Windows Live platform to Steam.

I have regrettably never played through Dark Souls, but I think shifting it away from GFWL will push it onto the list of things I’ll end up streaming later this year. (If I can ever get my streaming act together other than the yearly marathons.)
