Fuzzy bears!
I must have misconstrued some things, looks like I had it wrong, Did a little more research and it appears those games are available in Xbox and through Steam for PCs so from what I can tell know there are no Xbox games on Steam (for now). My initial readings seemed to show there were games for Xbox on Steam, I wish the idiots who write these articles would be more clear as to what they mean.
Sorry for the confusion, my bad.
Hell, I was shocked that I could play Steam games I had purchased on both Windows and Linux (where available). I was expecting to have to buy them again if I wanted to play on a different OS!
