There's been quite a bit of buzz over at the Japanese toy collector forums over this item. I've no idea what's the big deal about this set, but I like the idea of the set, with 4 figures and a whole lot of accessories.
This can be purchased from AmiAmi, which is Japan's largest online toy store apparently. Again, I have no idea. I just pick up Revoltech from bargain bins when I travel to East Asia.
Buzz and Woody are shipping now. Perhaps I'll pick up some of these since they look so fun.
