I'll assume Nintendo releases Fall 2012
If both Microsoft and Sony can hold of until Fall 2013 or later and release much more powerful consoles than Nintendo I can see Nintendo's console wiped off the market if Nintendo is unable to attract the "casual" crowd. Nintendo third party relations are going to be any better than they have been for generations.
Also if Microsoft releases Fall 2013 Sony can still safely launch early 2014.
