If they get it working then I hope someone/they bring it to the PC as well, I'd love to play some of my old 360 games again but my console died and I'm sure as hell not going to buy anything ever again from Microsoft (apart from some games on Steam).
I'd love to see them bring BC in, and not streaming. Just do it like last gen. It would be something to hold up as they wont be charging to play last gen games. But lets be real, these companies want revenue
