I'm almost positive it isn't going to happen, but I'd love it if part of Diana's exploration of the "Godsphere" including spending some time in the Dreaming. Heck, I'd happily read a mini-series of that written by the right author and drawn by a great artist. The closest interaction we've had between the Wonderverse and the Dreaming was a hint of it with Hippolyta in Morrison's JLA run, but I'd love to see a greater interaction with Diana. Anyway, just wishin'.
