There's been a variant of the TRU exclusive Batman 5-pack out for a little over a month now, but I don't think it was ever mentioned here. I got one a few weeks back, and thought I'd provide some pics.
The regular set is straight reissues of existing figures: blue JLU Batman, "Batman Begins" Batman, Zipline Batman, "The Batman" Batman, and silver TNBA Batman.
However, the variant features repainted versions of the JLU and TNBA Batmen figures, this time in gray. This is the first time either of these figures have been released in these colors, so it's a pretty interesting variant.
I haven't seen the variant in stores myself, a friend on the east coast got me my set.
