Picked up the 6" Dewback today at Kirkwood, MO Walmart. The neighboring Target had nothing new.
While at Walmart, I strolled by the clearance aisle and found a Kylo Ren Throne Room "variant". The figure was missing the cape, but the face had a Shazam facial scar done with marker, instead of his helmet, there was a custom melty Vader helmet (not sure if the person popped of Vader's head and tried to melt it, or used a knife to soften edges... maybe both). The throne room pieces were replaced by something else (not sure from where it came). I took pictures, but I can't post them here for some reason. I did send them via text to Chewie and Jodo, plus email the news link, so maybe you'll see it.
So, Chewie found a Rey exclusive variant at the TRU down the street, I the Kylo Ren, so I'm guessing there's a Luke out there somewhere.
