In Superman #1, launching in September, we will see what appears to be a new uniform for Superman. Based on the usual style, but more segmented with scores, seams or raised lines running across and around his arms, legs and torso. Kneepads as part of a segmented bulky boot. And a belt that reflects the Superman shield shape. And involvement in some form by George Perez. I'm also told Rags Morales may be involved with Action Comics #1.
And moreover, I'm also told Superman appears younger than we've seen him of late, almost Superboyish. Ultimate Superman?
UPDATE: The image given to USA Today seems to confirm some of this. A rejuvenated Justice League? Certainly an early twenties look. No boot or buckle though, see if I can fix that.
