TakaraTomy has made a dedicated page on their website for the
Rare Bone Ver. 2023 kits, which shows off additional images of each, and some nice dino-themed graphics. These two kits are scheduled to release at Dino Expo on March 14th, for 3,850 yen each (tax included.) I haven't seen a confirmation of an after-event resale, but the former Gilraptor Rare Bone was sold on TakaraTomy Mall after the initial event sales.
