TNI has an article with photos of the Batman/Clayface and Brainiac/Superman two-packs, with a release date of August.

[UPDATE: Kastor pointed out to me that this was actually posted on Mattycollector(!), so I can make the full-size photo available. Just click below to see it.]

I can’t help but notice Brainiac’s gun, a re-use from DCSH Lex Luthor, doesn’t appear to have a piece of kryptonite in it…still, looking forward to this set.
