Agreed, I wasn't even that excited for Odyssey (Mario Sunshine and Galaxy 1/2 just didn't really capture me the same way Mario 64 did). But man, was I in for a surprise. Once I started, I literally couldn't think of playing anything else until the very end. It really is a masterpiece in game design for just simply being fun.
So yeah, I'd love for the next Mario game to iterate on what made Odyssey so great. Wonder is fun and it's good, but it isn't close to being Odyssey good.
