I don't think it would be that easy , as microsoft isn't as indie-friendly as you think ... I don't think they would accept any game that easily
Very true, however XBOX ONE is supposed to be a lot friendlier to indie developers (A whole lot friendlier) Well that is what they have been saying because developing for XBOX has been a nightmare in the past, and caused lots of frustration.
More and more folks are realizing the power / demand of indie developers, so fingers crossed.
