I reckon he'll be there. We've seen precious little DC action but I'm tipping there'll be a buttload this year. The sculptor Andy Bergholtz(sp?) said the pics were taken a few months ago on statue forum.
They wanna WOW! everyone then the way to do it is show the Batman and Supes PFs off next to each other man. Bats maybe first quarter of 2013 and Supes 2nd quarter 2013?
I think they will be at SDCC, just not for preorder before comic con like someone else suggested.
