Three Hatsune Miku figures and one Nendoroid were included in Good Smile Company's WonHobbyG 2023 Spring announcements. All three are in different stages of development, with the exception of the one of a more stylized Hatsune Miku appearing alongside the Sanrio character Cinnamoroll.
First, here's the Hatsune Miku Symphony: 2022 Ver one. She is a scale figure, although she wasn't mentioned in the announcement. This means that she'll be unknown in size.
Hatsune Miku with Cinnamoroll is next up. Her facial expression and hair are both designed to resemble him.
The Hatsune Miku Happy 16th Birthday doll will be available as both a scale figure and a Nendoroid.
The Vocaloid's figures are often seen on television. For example, pre-orders for a Digital Stars 2022 version one have just begun in Japan ahead of its release in December 2023.
Any of these Hatsune Miku figures from Good Smile Company have yet to be released. However, the Symphony: 2022 Ver will most likely be released first.
