Nintendo owes us a new Metroid and they are producing Prime 4 right now, but we do not know when are we going to play it. To kill some time until Prime 4, the Big N could be working on Metroid Prime Trilogy for Switch.
Inet, a Swedish retailer, listed Metroid Prime Trilogy for Switch (currently down). The release was placed on June 17. Nintendo announced Paper Mario: The Origami King two months away the release, this is short, but feasible. Maybe date is not accurate, but Metroid Prime Trilogy was listed for Best Buy one year ago.
I want to believe.
Thanks, Nintendo Insider.
