|Personally, I'm hoping for the latter.|

So far, this is the cast list:
Brandon Routh - Atom
Wentworth Miller - Captain Cold
Caity Lotz - ?
Dominic Purcell - Heatwave
Ciara Renée - Hawkgirl
Victor Garba - Martin Stein/Firestorm
Arthur Darvill - Rip Hunter
Notably absent is Robbie Amell, who plays Ronnie Raymond, the other half of Firestorm. According to Greg Berlanti, there's a reason why Amell wasn't in the casting in the announcement for the show, but he "can't say why". Curious. Maybe Robbie Amell doesn't want to be tied down to a TV show and might have more of a recurring role? Or maybe they're going to replace Ronnie as the second half of the Firestorm matrix? After all, Jason Rusch exists in the Arrowverse, having appeared in The Flash episode "The Revenge of the Rogues", played by Luc Roderique.
Could always call it Super Buddies. Yeah!
Whatever it's called, the show is getting a 13 episode run, according to original Flash, John Wesley Shipp. Regardless of what it's called, which Firestorm they use, or how many episodes the first season gets, I'm totally hyped for this show!
