Haven't seen that these would found by anyone on JD, but I saw that two faced Vader, Darth Revan, Hoth Han and Shirtless Maul this am at a Wal-Mart. They were in a cart with some other various toys (it was during the time the section is stocked) so I'm thinking they were being restocked. I really wanted to get them, but didn't have the money to do it, so I had to put them back.
In particular I wanted the Hoth Han and maybe the Revan. I've got the first Maul and Vader, so those two are less exciting for me. No sign of Tarkin or Plo Koon, and there were only those four, no where in the Star Wars section, or Marvel, or Indiana Jones section were there any other of the new MMs.
