I think that Snyder did EXACTLY what the whole purpose of the DCnU and the reboot was: To simplify alot of confusing, convoluted crap for new readers. The original ideas (that of Bruce having a brother and then Morrison naming a Thomas Wayne Jr.) were simply conbined and simplified into ONE idea that made more sense than alternate realities and all that confusing stuff.
Also, a dream team-up I would LOVE to see: Hush and Thomas Wayne Jr. Imagine it, Hush trying to help Thomas gain control of the family fortune, both guys having a personal grudge against Bruce, not just Batman as most of his rogue's gallery do.
Duder, I LOVE the idea of Hush and Thomas Wayne Jr. vs Bruce! Who knows, maybe it's on Snyder's radar for the future?
