That first link just points to Nakashi's Twitter page (Nakashi is the web admin for Autobase Aichi). His Twitter page does point to the Seibu link (your second hyperlink) though. So if anyone wants to access info about this toy, just click on the kurdt's second link.

Meh... it's another fairly underwhelming black repaint. With the Autobot logos I guess he can be repurposed as "AllSpark Death Optimus Prime"... ya know, just before he gets revived by Sari's Key. ;p Good luck to anyone wanting this toy though as there's only going to be 300 of them available!!
