The Nintendo Switch is already rumored to have Mario, Zelda, Skyrim and Splatoon in its first year, but another major title may be on the way as well. According of Eurogamer, a site that has previously reported accurate Switch rumors in the past, a third version of Pokémon Sun and Moon will come to Nintendo Switch. The game is codenamed Pokémon Stars, and has apparently been in development alongside Sun and Moon on 3DS. The article even points to the announcement video of Pokémon Sun and Moon from the Pokémon Direct back in February showing an HD Pokémon model for the Switch version.
While the article states that the game was originally planned for a summer release in 2017, the team prioritized finishing up the 3DS game before returning to the Switch version and will release later. The Switch version is said to take place in the Alola region and use the same art style, but with all new HD assets. It would be amazing to see a mainline Pokémon game on a Nintendo console, especially with the franchise coming off a spectacular 20th anniversary celebration. Only time will tell if this rumor is actually true.
