For a while Metroid Prime Trilogy and Persona 5 have had a number of rumors suggesting both would eventually land on Switch, with the latest coming from Best Buy.
According to Best Buy’s CoreBlue, a number of new SKUs were added to the system. These include, but at not limited to, Metroid Prime Trilogy, The Legend of Zelda: A Link to the Past and Persona 5. Their listings, which contain mostly placeholder data, mention they were just announced and more information would come soon.
Given that Atlus is teasing the reveal of Persona 5 S on April 25, S obviously might stand for Switch and Joker is the next Smash character, it seems more than likely this is accurate.
As for Metroid Prime Trilogy and The Legend of Zelda: A Link to the Past, both seem entirely possible. Metroid Prime Trilogy has been the subject of a lot of speculation following the reveal of Metroid Prime 4 and given it was delayed, it makes even more sense to use this to fill in the gap. However, The Legend of Zelda: A Link to the Past seems a bit out of place.
Considering we’re getting a remake of The Legend of Zelda: Link’s Awakening, it would be uncharacteristic to announce another remake. This might be a listing for a digital copy, something Best Buy also sells, though this would also be the first non-subscription based Virtual Console title, making it equally unlikely. I’d also guess that maybe someone mistook Link’s Awakening as A Link to the Past, if it wasn’t for the fact that is already listed on the site.
Hopefully we will know the truth in the foreseeable future.
