It makes absolutely no sense to announce a product which won't released until months at the begining of the big shoping period of the end of the year. A november reveal would be stupid. "behold the NX, the wondeful console your kids will want for christmas but that won't release before march of next year!!!", and the malls would see average moms asking for this new nintendo console their kids asked for, only to answer them that no, they don't have it.
It has to be october.
If it is not, then the thing is probably delayed, who knows by how much months, which seems unlikely to me, cause Nintendo would have naught to cover the first half of next year.
I don't know. It should be simple. But it is so circonvoluted.
