Re: speculations about the delay possibly being in order to feature a JL accurate head sculpt, I really doubt it as this is what they were showing at Tokyo Comic-con only two months ago (see at 1:40):

This is strictly a matter of personal taste but I actually wasn't crazy about the way Henry's hair laid parted on the other side in JL. For me, the stern looking BvS head sculpt gives him the gravitas that matched the vibe of the character in BvS. To get that repainted and a brighter, warmer colored suit is exactly what I'm looking for. It's an alamgamantion of BvS and JL in a sense. And honestly, until I see the Snyder cut (and we will see it eventually) I'm reserving judgment on how Superman is depicted in JL. I'm not loving anything I saw in Josstice League. But that's a subjective taste thing, so please appreciate it as such. If others loved the theater release of JL fwiw they have my respect. Who am I to tell someone else what should strike a chord with them?
