It might be another Amazon Glitch, but the world's biggest bookstore currently has listings up for seven DC Universe Classics Figures that haven't been released or announced yet, most of which have been rumoured for DCUC Wave 15. They're listed as "Out of Stock", with no photos as yet.
These are: (follow the links to the Amazon listings:)
Martian Manhunter (according to the listing, will have an alien head variant)
Starman (according to the listing, a 50 / 50 classic / modern split)
Is this the real Wave 15? Will Amazon get in trouble for jumping the gun? Time will tell!
You can discuss all this and more in the AFB Forum DCUC Wave 15 Speculation Thread.
