Remember that Nintendos current CEO Tatsumi Kimishima is only constitutionalized, until a 'real' CEO is chosen, to lead the direction. Until then Tatsumi will probably only utilize on the Iwata strategy laid down, years ago.
But yet again, we see Nintendo now completely softening their approach to mobile games, with pokemon go and super mario run.
My point is, the Nintendo we have known for years, is not the Nintendo we see today. They seem to approach things slightly differently. Which is why a reveal in october is plausible, because why not.
Also they seem to be extremely tight lipped about the NX, which is a better reason to withhold an official anoucement for just before launch.
