I have no idea what's going on with these characters, since I don't buy anything with Superman in it any more and dropped anything with Wonder Woman shortly after Brian Azzarello's run.
That said … well, I've always kind of gotten a kick out of the "T-Shirt Superman" outfit from both the old Superboy days and the Grant Morrison era, so that (aside form the size of the logo) doesn't bother me. At least for a while.
But Diana's outfit here? Egad. Start with the silly wrist blades and go on to a thousand decorator accents and gold sparkly bits. It's way too complicated and, frankly, hideous (and it will be a nightmare for multiple artists to draw it consistently).
Oh, and, really? If Superman is getting out from having a Jim Lee Special High Collar, we have to give one to Wonder Woman? Yeesh.
