And bunch of other names. Altough some of them will be part of Pikmin 4 dev team. We will see in July.
Mario Maker 2 released in June 2019, Octo Expansion in June 2018. That means that some concepts/prototyping of this game has to be happening from 2018.
I feel like the artstyle of this game will surprise people a lot, maybe something from Kotabe’s art? More 2.5D ala 3D World style in Maker 2? Clear conditions for levels this time as in Maker 2? We can all agree that New Super Mario series is dead.
We've been seeing more of Yoichi Kotabe’s classic Mario art lately in marketing and other places, like the character select screen in Super Mario 3D World. Will we ever see a 2D game made entirely of Kotabe’s art?
Miyamoto: We’re at almost like a turning point. When you look at Mickey Mouse there is the classic Mickey Mouse, and then there is the modern Mickey Mouse and the classic one has a lot of flavor to it and the modern Mickey Mouse looks really great, but it is losing a little bit of the flavor, and that’s something we discuss to make sure we keep that intact as we’re creating characters. And of course the development team for any Mario game may want to use Kotabe’s art, but there is also a character-development team that’s really working hard to create new styles and new work. Once they get more work done, I think more and more of that will be reflected into games.
And you feel like the pristine, perfect flavor for 2D Mario is that beautiful, clean Kotabe art?
Miyamoto: I do believe that Mr Kotabe’s art has become kind of a standard within Nintendo, but we definitely want to continue to see if we can evolve that as time goes by.
As to when this game gonna be announced, it can be as soon as 2-3 weeks from now. For a late October/November release. Most 2D Mario games had a fairly small reveal-to-release cycle:
New. Super Mario Bros. Wii announcement at E3 2009 - November 2009 release.
New Super Mario Bros. 2 announcement in April 2012 - July 2012 release.
New. Super Mario Bros. U announcement at E3 2012 - November 2012 release (altough this one is tied to hardware launch/reveal). "The prototype NSMB Mii. was shown at E3 2011".
Super Mario Maker 2 announcement in February 2019 - June 2019 release.
Every New Super Mario Bros. game apart from like DS and original Mario Maker had a 5-6 months from reveal to release, or even less. If Nintendo wants to sell 15 mil. Units this FY, new 2D Mario game is exactly way to go, especially after Mario Movie.
