In a new trailer that was released at D23 Expo in Japan has revealed the new look of Riku in Kingdoms Heart III, in more recent news an action figure of Riku has also been released.
Bring Arts made this announcement not long after Square Enix revealed the new trailer for the game. The new Riku figure will also be accompanied with two new figures of Sora, Halloween Town form and Christmas Town form, both from Kingdom Hearts II.
Following the reveal of the Toy Story world which happened awhile ago, Bring Arts also announced after the reveal a slew of Toy Story figures, so this isn't an unusual thing to happen after an announcement.
