A theory for a while now is that either botw2 or odyssey 2 will release this December to keep Switch in the spotlight with next gen.sounds like wishful thinking on the part of fans that just want what they want.
Yeah if it's just these ports and paper mario for 2020 that'd be a big downgrade.
i mean, i guess it would be great for some. but diversity in a line-up is a good thing imo. mario is good but nothing but mario is not good especially if a lot of them are just ports of old games (even if remastered).
