I was watching some Ori and the Will of the Wisps on the Switch and I started to think about this.
Metroid is one of Nintendo's legendary franchises, but in terms of sales it's a very modest one. So, wouldn't it make sense to expand its reach? I think there might be an entire new market for the Metroid games, especially the Prime trilogy, if that happened. And I don't think Nintendo has much to lose here, it's not like people will stop buying their consoles to buy a xbox.
I don't know how close Microsoft and Nintendo are, but if a game from Microsoft Studios can be released on the Switch the other way can happen as well surely?
I want more Metroid...
