It would be awesome, and probably not much time to release an aneversry edition to bring DOAX the first one to the Xbox 360 in HD.

Or atleast work on a patch to make it playable on the xbox 360

They could probably release it on Xbox originals. They could also put the DOAX2 on the Live Marketplace if they haven't done so already.

I don't think Microsoft is certifying anymore Xbox games just for BC. Releasing the product in stores likely would not be worth it for them.
