Could be sequel setup. Would make sense to introduce Tails and Knuckles.This shot is interesting to me, because the new trailer shows that at least some parts of the movie actually take place in actual Sonic stages like Green Hill, and it actually looks authentic.
What is this supposed to be? Mushroom Hill?
Either way, this is a significant upgrade. It still will be a goofy kids movie, but at least it doesn't look nightmarish.
