Just wondering if anyone knows whether DC Comics and Warner Brothers will be releasing a card set for this film with autographs and relic cards?

I have seen zero mention of it on any schedule. There is no set that includes the current movie Superman either.

Probably a very expensive license that would have a lot of restrictions on content with no guarantee that any name actors could be signed up for autographs.

There are some promo cards about released by Warner brothers ,( 8 I think ).
