No real reason. Xbox live did not stop supporting the original Xbox until 2010 which was roughly 9 years after launch and about 5 years after the 360 came out. Given that pattern the 360 should be supported on live until 2018 +/- and will of course still work as a stand alone unit until it red rings.I guess I am just not getting this. Why would you not be able to play it on 360/PS3? Just because a new system comes out doesn't mean they brick your old one. I still have dreamcast, PS1, master system, N64 and gamecube games I have yet to start and finish along with a ton of others. I have almost every major console that has been released and I have never not continued to play the games after the new system comes out.
