Right after E3, Koizumi-san joined the Nintendo Treehouse presentation of Super Mario Odyssey.During their gameplay, we could see so many new features, like the Bullet Bills that you can take over, the 2D/3D mixing when going up certain buildings, the ability to buy items with the coins you collect like different hats.
A clear mention was made that enemies with hats are the more powerful ones. At one point, they started playing, what appeared to be, a boss battle.
During the treehouse, they also announced new Amiibo!
