This one?
I'm pretty sure it's Central City. I'm fully expecting a Flash Museum break-in as the stage transition.
I think you are probably right. Plus we haven't seen a Flash stage otherwise so it makes sense. The stage in question also appears to be the one in the Green Arrow/Hawkgirl promo image. I am betting they will save its "reveal" for the next Flash fight in the battle arena.
The stage I really want to see the most of right now out of the ones we know of is the Hall of Justice.
