During Nintendo’s Spotlight Event at E3 2017, The Pokemon Company announced that they are working on a brand-new main line entry in the Pokemon RPG series. The entry is more than a year away but this would be the first time that a main Pokemon game has been on a home console. Genius Sonority developed two Pokemon RPG’s for the Nintendo GameCube (Pokemon Colosseum and Pokemon XD: Gale of Darkness), but they were not in the true fashion of the main line entries that were developed for handheld systems.
Nintendo didn’t say whether or not the entry will be the start of the 8th generation of the Pokemon franchise, but we can only assume. If the 8th generation of Pokemon isn’t on the Switch then a remake of Diamond and Pearl could also be likely.
The Pokemon Company did not release a launch window for the Pokemon Switch title, but we can expect to see after at least a year.
