Shortly after the Famitsu Magazine details were leaked to the world, the Pokemon Company went ahead and confirmed that Pokemon Ultra Sun & Ultra Moon will be the final Mainstream Pokemon Games released on the Nintendo 3DS. It is not known if Nintendo is in the works of a new Handheld System or not - as the Mainstream Pokemon Games have only been released on - but, at the time, it appears as if the next set of Mainstream Pokemon Games (presumably the 8th Generation of Pokemon) will be done on the Nintendo Switch. If you recall, Pokemon Producers confirmed earlier this year that a Mainstream Pokemon Title will be released on the Nintendo Switch sometime in the year 2018.
