Truth is the biggest game developing companies like bungie, valve, EA, would not because they are companies that believe in either multiplats, or wide distribution.
Other than that if you have no 1st party support you are screwed.
After MS venture into the foray many companies are scared shitless by even thinking of the console market. MS has barely made anything in 7 or so years and they HAVE HAD 1st party support for many many years and have software brandname.
The ONLY possible way would be if a massive wealth bought out many game devs.
Or, with major mod community backing. Something like newgrounds.com.
FYI: There are other consoles on the market other than ps3,wii,360. You just don't know about them because that is how hard it is to compete with the big boys.
