I think its going to be Thawne as the Reverse Flash, just speculation on my part obviously but RF watching Barry with Iris and not killing or even hurting Eddie when they came face to face.
so Krypton on the Syfy network is happening. It follows Superman's grandpa. So we might have 2 shows next year (Krypton and Supergirl) that are associated with Superman but never mention him.
I thought they would just stick him in the next xmen movie. I dont know if the character is strong enough for a solo movie especially since Rogue really can't be his love interest in this universe.
