Personally I think Prometheus-X is going to be the Earth-X Oliver Queen and the Earth-X Green Arrow will be somebody else, maybe Roy Harper since Colton Haynes is said to be returning soon. I think it would be an interesting parallel since E1-Prometheus was kinda a mirror to Oliver Queen and what he could've potentially been, so it be interesting for Oliver to see that in another life he did become Prometheus. It would also be interesting for Curtis, Rene and Dinah as the Team Arrow newbies to have to fight him as they'd basically be fighting their leader.

Of course the mobid side of me kicking in now if EX-Prometheus is EX-Oliver and Felicity doesn't die in 6x01 like I'm hoping she will it would be poetic if EX-Oliver killed her in the crossover.
