As for the Zeta movies, there's a thread here (you have to search for it) but Tomino had said on record he wanted a "happier" tone for Zeta's ending. Less casualties as well from what he was saying. He also said Camille's character was going to be modified some as well.
Translation: he got soft, and wants to modify his dark series. How he plans ZZ and CCA to still fit in I have no idea. He isn't "kill em all" Tomino anymore.
Honestly, I think it just means he's writing out ZZ, nothing he does should effect CCA.
