how bout asking a few of the millions of talented coders that do those things for free if they would do it? give them some money and they gladly do it.
ive seen things like quke run on wii. ive seen things like N64 games run on MAC. ive even seen sega saturn games run on linux. and those programs are free. coded by maybe two or three people over the course of a year or two with permanent updates to the core.
those people do that in their free time, you cant just tell me that it would be impossible for a group of say, ten coders that work only on opeGL support.
as said, forget the console gaming thing. you just cant afford it. sure, you can develop for XBLA for free, but then you may not sell the game. way to go. if you want to sell it, shell out 30k in cash first.
and if you dont have your own office not located at home, you arent even going to develop for anything else, because thats one of the main things for consle develoment.
and as ive said, as long as you cant even efford nice models...
