Having the series on the Switch could likely reduce the process load and leave enough room for the game to run smoothly on docked and portable modes at 1080p. The Prime games also pushed the Gamecube, Wii and DS systems to the limit while rendering graphics at a targeted 60 frames per second.
Last year, the company announced Prime 4 would start over, with original series developers from Retro Studios taking up responsibilities again. However, the initial project was scrapped by Nintendo after producers deemed the game not up to par with their expectations. It makes sense for the Prime Trilogy to eventually make its way onto the Nintendo Switch console following the announcement of Metroid Prime 4 in 2017.
