You guys do remember that the TF line is practically dead in Japan right now, right? It's far from a transforming robot utopia at the moment, although they have had some pretty awesome periods in the past. Thankfully many of these blasts from the past are available on Yahoo Japan auctions- I use a proxy service to bid on stuff on there. It's kinda expensive, but the exchange rate is great right now.
http://www.shoppingmalljapan.com if you're wondering. Expect about 9,000,000 movie-exclusive Bumblebees to be on there in about two months time.
