Impossible to tell, wild guess anyway.
I still see the 720 winning as the US market will be the decisive one more then ever. The Japanese market for consoles will shrink in favor of handhelds and the European will because the 7th gen consoles will remain 'good enough and the ungoing financial problems in some countries will hurt sales in the first few years.
I see the total market shrinking. 720 wins, WiiU and PS4 tie and could go either way:
XBox: 85m
WiiU: 65m
PS4: 65m
