That's pretty much what's already happening. Nintendo is saying:
"If you don't 'innovate' the way we tell you we dont want you as a developer"
and a few like Sega, Capcom and Namco will say:
"okay we'll give a try with one or two games"
but most others will be like:
"I can't hear you over the soundtrack to True Crime 3!"
or something similar.
