Not to be doom and gloom again, but if it doesn't announce in October, I don't think it releases in March 2017.
I have no insider knowledge am not involved in videogame industry what so ever.
But at this point, I think something has gone massively wrong. I personally believe that NX was intended to launch in November 2016. Then pushed to March 2017. If that does not happen, then something is up.
Maybe they had to change specs, maybe something happened with production run, maybe they are trying to be purchased by Apple, Disney Google, Microsoft or someone else. But something is/could be up. Google and Microsoft both are supposed to have events this much.
I also don't believe they currently have the robust third party support people on the inside are claiming. I think it is very much a "wait and see approach" with western third parties.
I think they are praying Pokemon, Nes classic, and Mario iOS can carry them thru this holiday. I have felt this way for a while, as brilliant as Nintendo is, and they are. Nintendo may be out of their depth at this point. They may need to partner with someone who can help with online infrastructure, and or facets of a modern system.
That being said, I firmly believe that this is going to be a system for children. It seems like the appropriate market to chase if you are Nintendo. They will abandon the hardcore, and teenager and up crowd for the most part.
