I have the weird feeling that this will be targeted and speed runners. The camera angle and how the rings are positioned makes me think Nintendo wants players to get as fast as possible through the course, with a new special jump through those rings for instance. Just a thought.
Somebody on Twitter astutely pointed out that, indeed, those are rings and not gold coins. Sega is also listed as a partner, though that could be for anything. With the recent 3D Sonic-like perspective, I don't know if I would be super surprised if this is some sort of crossover.
