Filming has started, and several teams have been spotted.
So far, the only identified team is Ally & Ashley - cheerleaders.
Other teams seen are:
Tall black male team
Another male team, both quite a bit shorter
Another male team wearing blue bandanas
M/F team, girl has pink hair
M/F team who might be our older couple this season
Long haired bearded male team
Boston M/F team
That's 8, so three are yet to be seen. So far, no reality retreads.
