i have been trying to contact people about this at xbox for ever and never get any response. i will be pissed if it isnt because i dont have my regular xbox anymore. 360 was expensive, needed all the credit i could get towards so i traded my xbox in. i just REALLY want to know if its going to be backward compatible. i only got to play a little bit of painkiller at a friends house because my pc is crappy, but i LOVED it and have been waiting for this forever. also, anyone know if the future xbox game black will be backward compatible either.
