If I remember correctly, they mentioned Professor Ivo was involved. Or T.O. Morrow, one of those two. And Ivo built Amazo while Morrow built Red Tornado. But, what's Vandal Savage's state in the New52?
I think TO and Red Tornado are Earth 2 in the N52. In Earth 2, Red Tornado's body has been seen, although now it is a female android. Can't remember if they mentioned TO or not but it stands to reason that he would be in the same universe as his creation. Ivo won't lead, but I can see it being him. Don't remember if he was mentioned or not. I think he was when they retrieve some circuitry or something.
As for Vandal. Aside from Demon Knights, he has also turned up in Gotham in the 1800s where he squared off against Jonah Hex and tried to take the old Wayne family hostage. Savage also appeared in DC Presents, but I can't remember if he escapes at the end or ends up back in jail. People seem not to believe that he is immortal in the present day N52, his daughter certainly doesn't.
