Zelda is better than those games...tho.

None of them are out. I'm not sure how that claim can be made. 

OT: Someone mentioned September. I agree that such a period would better for this sort of launch!

Well they have said March 2017, but this is Nintendo, so September 2017 is still not out of the question...
