I really like the Tanuki, probably the best of the 'Japan' set from RxH though it lacks the usual mutated touch.
http://ameblo.jp/uamou/ Uamou (Ayako Takagi) posted on her blog about NYCC '12 presales for her collaboration with RealxHead. If that's not enough, she mentions Mori being there selling stuff too, so there might be more coming along from RxH we have yet to see. Pretty exciting either way. Fingers crossed.
I met Ayako last year, and she was an absolute wonder in person, but I've yet to meet Mori. They're two of the three people destined to drain my wallet too. Hopefully they'll both be there when I'm there.
As far as I know he will be at the Onell booth for the entire con. Schedule will most likely be ad hoc.
The tentative schedule is that RxH, Uamou and Skull Toys will be at one of the tables for the entire con.
Ayako had two colorways of her Uamou x RxH up at the Con Today. Black with white accents, and an all silver brushed looking one. If my phone wasn't dead, I'd throw up a photo. Sorry!
I wasn't going to show it off, but someone over at OctoberToys dropped some teaser images of it already, so I figured "What the Hey!"
