This is going to be difficult to obtain first-hand, as Amazon Japan don't usually ship toys outside of Japan. (a bit like Amazon US - but they made an exception for Unicron last year)

Release details have been posted up here, from the Amazon.jp page:

Date - August 25 2012
Cost - 13,650 yen (about AU$160)


I couldn't see anything on the product page saying that it was restricted to JP purchases only, but if someone already has an account with Amazon.jp, let us know if it allows you to pre-order it to a non-JP address.
