Thanks, Santa. This is just what I always wanted. Now I can play Live Arcade games with my non-Xbox 360 owning friends. Better yet, I can play Uno with my mom!
CVG thinks that we should expect to see the Live Arcade that we all know and love show up on Games For Windows - Live by this holiday season.
1UP mentioned that Microsoft was about to release dev update for Games for Windows tools "in anticipation of Xbox Live Arcade games rolling out in holiday 07."
Destructoid has heard similar rumblings (and maybe even saw it in action), so a pre-Christmas is definitely not out of the question. In fact, we'd bet that Uno will launch at the same time.
Hey, a web cam would be a nice stocking stuffer for mom.
