It looks like they are going to be another limited one. Kinda like the DW1.
Only a couple even in a bin. I opened a brand new 72ct shipper and only found one in there along with a surf crate and a bat. They seem to get the same distro as a regular treasure hunt. At least in my experience.
I would guess that seeing that the Chinese calender for 2013 is the year of the dragon that Mattel would make a "limited" release of an otherwise normal mainline casting.
If I see it I'll pass, I never liked this one anyway.
