Yeah.
When he brought up that he was doing either a Superman mini or a Marvel event a couple months back as a break from creator owned, he unambigiously stressed that whichever he chose to do first, both would be happening over the next few years, and he laid out plenty of what he'd be doing with Superman:
* A six issue mini with the artist already chosen (who isn't going to be Bryan Hitch, John Cassaday, Jason Fabok, Jim Lee, Matt Southworth, Daniel Bayless, Dan Mora, Leila De Luca, or Carlos Pacheco), this is a further reworking of the ideas from his dropped Superman movie trilogy that were originally going to be part of an OGN.
* Super-powerful, super-smart Superman. Clark and Superman are two distinct people, with Superman as the true personality.
* Fairly little focus on the supporting cast outside of Lois (Daily Planet has a minor role, Ma & Pa are long dead), Lex and Brainiac are the two big villains. Darkseid and the Phantom Zone might be involved too.
I'm thinking a 2018 release for that is a near-given, since that's Superman's year with that as a potential crown jewel, and whichever artist he picks will probably need awhile to work on it.
