MS has said that there will not be backwards compatibility between the 360 and the new system. It remains to be seen whether previous owners can get free (or massively discounted) ports of their 360 purchases, but until I hear different, I'm going under the assumption that it will not happen.At this point,I just think it would be good to wait to get the info on the upcoming Xbox 720/Infinity/whatever it's called - see if any of the DLC from the 360 can be transferred over to it or not. I had plans to buy all the DLC,but with this long hiatus,not anymore. I'm not into buying things twice,like the PS3 owners will seemingly have to for the PS4.
