"Order Dates: Orders can be placed between the 8th December 2014 (Mon) from 12:00JST until the 30th January 2015 (Fri) at 21:00JST."Actually (new) Sakura Miku was still open for preorders like just last week at GSC so you're not way too late, just too late enough! You'll have to wait until release and buy her pre-owned or from some other reseller at markup, because she's only being sold from GSC shop.
It was only 2-3 days ago! NOOOOOO.
I wasn't really a fan of Miku until recently, so I wasn't even thinking of getting her special editions until now.
