A new entry in the Super Mario series is upon is! We are just days away now from the glorious Super Mario Odyssey! Run, jump, and explore your way through plenty of 'Kingdoms' setup similarly to the great Super Mario 64 and Super Mario Sunshine! This is the Mario game everyone has been waiting for!
Check out Nintendo's now-famous Super Mario Odyssey 1:30~ long commercial!
And check out some of the glorious screens as well! Soon you'll be able to use the special mode found inside the game to pause the action at anytime for a photo, but you can also change the angle in anyway way also. Quite a neat feature.
I'd actually personally like to see a direct sequel a la Galaxy 2, as similar to Galaxy 1 I feel Odyssey has a lot of potential and could easily fill a whole new game with a slew of new kingdoms, enemy abilities, and outfits. There's so much which can be done not just with Mario's base moveset, but also the capture enemies, that I could see the dev team having a lot of leftover ideas they didn't have time to implement in the same way Galaxy 2 was born.
As for the timeframe, since it would reuse a lot of assets from Odyssey then the dev time would be shorter. Something to keep in mind about Galaxy 2 is that its release was actually held back to space it out from NSMBWii's release, it's tough to say when it would have released if not for that game but the point is that it was ready to go ahead of when it was released. With this in mind, I could see an Odyssey 2 making the holiday period of 2019, though depending on what else they have planned I wouldn't be surprised if it's the May 2020 game.
