Tony Daniel has posted the cover sketch for Batman #687 and has promised some design sketches for Batman and Robin soon:

QUOTE:
"The design is by Andy Kubert. I will later post a couple of my design ideas here so people can see what I was thinking for the new look. In the end, DC and all the big wigs and WB stuck to something very close to what Batman already was. Which is fine, because, you know, people hate change, right? My Robin design was chosen and he was a bit easier to approve. I'll showcase some of the Robin design sketches soon too."
