Oliver Queen and Barry Allen switching costumes and (presumably) powers is not the only wacky thing we'll see this year's Arrowverse crossover.
The annual Arrowverse crossover events between The Flash, Arrow  and Supergirl have been extremely popular with fans as they've grown in scope each year. That's changing this fall as Legends of Tomorrow sits this one out (though it's got something special planned as a meta-style response), but with the return of Superman, the debut of Batwoman and the "Elseworlds" title , anticipation was already plenty high.
Stephen Amell may just have figured out a way to stoke those fan flames even more. We already knew we could be seeing Amell as the Flash and Grant Gustin as Green Arrow in "Elseworlds" thanks to the poster for the crossover,
But they'll be getting company as well in the form of another speedster, one who should be familiar to viewers of all ages. Here's the "Elseworlds" pic that tweeted out today. Twitter in a tizzy:

First chance: It's simply Shipp reprising his role as Jay Garrick, the Flash of Earth's Arrowverse's, and he's either adopted that suit in a callback to the prior TV series. Option 2: Whatever timeline trickery that is responsible for the Oliver / Barry swap messed with Jay's costume as well.
Then there's the third and arguably most exciting alternative, which is that somehow is the 1990 Barry Allen. It is not certain that the universe is considered as the "Elseworlds" concept, which in the comics means "universe in only one or two important ways". 19659008] Next: Supergirl season 4, episode 2 recap: Fallout
Regardless of the reason, they have been talking as much as they can during the build-up to the crossover. "Elseworlds" kicks off on Sunday, Dec. 9 on The Flash, continues on Arrow on Dec. 9 and wraps up on Supergirl on dec. 10.
