These are just my own expectations based off that one small review we got so this is more speculation,
I feel the characters in the race will definitely not be AAs, I’d think if anytbing just at the starting line bit even then, im imagining you’re able to tell the difference between AR and real sets relatively well, unless the AAs are insane, I don’t think they can do it on the ride and have them both working at the same time. Either the scene is full of AAs, or it’s filled with sets with the characters all around us, and to be honest it would make sense.
My only hope for an AA character is the volcanic Bowser from MK 8 Bowser’s Castle, we got Kong in Orlando, this is so big it wouldn’t matter if its AR or real because of its pure size, so idk, that’s my hope for rn. I’m just so damn excited to see the thing haha
