I have to say if that Wave 20 line up is in fact true, I have no problems with it. Only one I'd prefer to not be in there is Nekron-he does not warrant a C&C; could easily be a regular figure, and should have been in one of the GL Classics waves. (Give us a Doomsday C&C already!-Hell, Atrocitus could have been the C&C choice, as he's nearly Kilowog's size)
GA Supes is long overdue, (along with GA Bats), Vandal Savage is welcomed, and, depending on how he's designed, could FINALLY pave the way for some civilian-type looks for figures. Not big into Manhunter's character, but his design is unique enough that he'll stand out on the shelf. (Plus the SP tie-in) Arisia & Atrocitus are A-OK by me, and Guardian will depend on which one. If it's the modern version of the one from Wave 9, I'll pass. If it's Ganthet, or one of the other GL Guardians, I'll take it. (Though they could easily put 2 of them in one package or include Ch'p, etc...)
And for all the GL complaining, I wonder who will complain if/when the majority of DCUC next year turn out to be Bat-related?
