I've personally said that they're going to release their next home console in 2017. That's not because they should, but because they are. Most people are in agreement that by holiday 2016 Nintendo will have probably released all of their heavy hitters once, so it's safe to assume that they probably will release a new console by 2017, with 2018 being the absolute latest. Also, their home consoles don't have very long lives as well.
The next PS/Xbox won't probably release until 2019 at the earliest (it could be longer) and I just don't see Nintendo holding on that long to release their next console. I do agree though that the ideal situation for Nintendo would be release them around the same time as the other next-gen consoles, but it's just unrealistic to think that it could happen.
