Thanks. I read over that page but was looking in the text rather than the title, doh.
Slave 1 -- 4,104 Yen
AT-AT -- 4,200 Yen
Falcon -- 5,400 Yen
That 4,200 Yen price places the AT-AT just slightly higher than the Slave 1... which usually runs about $32ish imported, and the Falcon, which runs $40ish imported (I'm talking the amazon/ebay price with shipping, not currency conversion). Hopefully stores won't be pricing it at the full $48 srp because if so it seems like there is little motivation for a local purchase if import costs continue as before...
Edit: My comparison is with the import price, not the price in Japan, but it's the same story with the scout/speeder set - imported on Amazon it goes for about $38 (even a direct currency conversion of the Yen price puts it at $47, less than the US AT-AT price), and this is despite its Japan retail price being 28% higher than the AT-AT.
