Odyssey is the most ambitious and hyped Mario game SINCE Galaxy 1, and with it being on a handheld like device like the Switch, it automatically gives it a chance to beat 3D Land as the best selling 3D game in Japan, it's beating it in COMG pre-orders thus far.

So, it has a chance. A tough one, but also a good one.
