After building up to the reveal of Nendoroid 300, some fans were a bit let down by Good Smile Company announcing that the coveted spot would be going to Hatsune Miku, mostly because the changes made to the 2.0 version are somewhat insubstantial. Even if that doesn't stoke your fire, GSC also previewed a whole new batch of Nendoroids planned for 2013.
Changes to Miku include a slimmer body, glossy clothes, head assembly with a separate neck piece, and some new poses.
UPDATE: Miku 2.0 is available for pre-order at the Crunchyroll Store now!
Now onto the rest of the new Nendoroids, which include Append versions of Len and Rin in black and white outfits, Sakura Kinomoto (Cardcaptor Sakura), Houki Shinomono (Infinite Stratos), Kobata Hasegawa (Haganai), Rin Natsume (Little Busters!), Miho Nishizumi (Girls und Panzer), Ren and Darth Wooser (Wooser's Hand-to-Mouth Life), and Monokuma (Dangan Ronpa).
