I appreciate all of your feedback, but the truth is I feel that the XNA your talking about osnt the same XNA I saw been reported on the BBC program, "click online", and the target market stated in the program was hobbists and small independent developers. The XBox compatabitilty comes through a subscription service, where by all accounts they will convert the software for you... or something.
How old is your information, I saw this the day before the original posting. Anyway I hope im wrong... but what if im not?
