I bought Willrow the first time I saw him, pretty much to show support for obscure characters in general. He did eventually start to warm but once the price went down to 4.50 at Wal-Mart and Target he cleared out.
I had to buy up several Leesub Sirln's just to get her off the pegs considering she was a figure I lobbied hard for and I didn't want to see her warm forever. I still have a couple if anyone's interested in them.
Captain Colton is still warming at my local Wal-Mart and he's a figure I have no interest in whatsoever so I probably won't be getting him. He's the only Legacy figure left on the pegs besides some Legends Obi-Wans.
Overall I'd say the new lines are selling very well, and hesitate to call out any true pegwarmers just yet. 4-Lom I don't believe will ship in any other assortment than this first and a revision so I'm not too worried about him. I am a little puzzled by his inclusion in Target's exclusive 9-pack though, a Stormtrooper or Bossk would have made more sense.
