Will our gamerscores carry over? Will all the stuff that I bought.. arcade games and Zune market place be downloadable on the new Xbox? Will I be able to use my account on the 360 and the new one? How long will we be able to play 360 games online after the next one launches? Curious-Does anyone know if you can you still play original Xbox games online? Just some things I have been thinking about. Thoughts?
