It will not have third party support at all. Since Nintendo not being a retarded moral-less shit company is the problem NOT Nintendo being underpowered.
But since Nintendo would own all of MS IP i think it does not even need most of the third party games
Also Conker Banjo JoannaDark MasterChief MarcusFenix etc in Smash? + AgeOfEmpires Forza and Freelancer etc. assist trophies? Hmm why not?
Tbh. I would buy a NintenBox probably day1. (as long as it just as a XBLG fee for people that want online tournaments) and has free online as long as you play with people in your friendlist.
