Hasbro axed the line before they could produce a number of new Animated moulds, and were only just able to sneak out four of those figures to US TRU stores (Arcee, Rodimus, Cyb Ratchet, Cyb Ironhide).
The rest looked to be lost, until TT started producing the Animated toys, and hope returned that we would see them released in some form afterall. It would just be more expensive for Animated fans to fight over the limited JP stock.
Anyway...
The next two unreleased toys to be released in Japan are Wingblade Optimus and Hydrodrive Bumblebee.

Plus a couple of transparent redecos it seems, and Rodimus Major (probably end up being in stores at the same time as the US release).
And - the Optimus Megatron 2-pack is listed as both Cybertron modes (the Hasbro 2-pack had the Earth mode Optimus with Cybertron Mode Megatron). Could either be a misprint, or TT have swapped over the 2 Deluxe sized Optimus toys for their 2-pack to make more sense as a verses pack.
