Looks like Wave 5 is out in Hong Kong now (while we are still having trouble finding wave 2 in most stores here).

Some pics have been posted up of the Kup toy, in and out of packaging (mirrored here).

Note - Kup was originally planned to be Ironhide, but was changed by Hasbro (possibly after Ironhide was replaced with Bulkhead in the cartoon), but TakaraTomy are still releasing their DLX mould as Ironhide.
