Here are my predictions:
-Metroid Prime 4 won't release this year, it will either be a 2021 release or it'll be delayed to that year.
-Stadia will close its doors after quite a lot of money lost.
-FFVIIR won't come out this year either.
-Another mainline Pokemon game will be announced, either a Let's Go or a sequel of Sw/Sh. And everyone (including myself) will be pissed of the annualization.
-The 3DS line will end in 2020.
