In today’s Nintendo Treehouse live stream, Nintendo has confirmed that 2 player co-op is indeed present in Super Mario Odyssey. One player moves Cappy whilst being able to float around and take flight around Mario. Whilst playing as Cappy players can also grab hard-to-reach items. The other player moves Mario and controls the camera. Other control methods haven’t been discussed yet but holding the Joy-Con horizontally is how they’ve showcased 2 player co-op so far.
