The red Rampage released in Japan earlier was not the new mould (coming soon from Hasbro), it was a repaint of the one from the combining set and given away for free by TRU JP for buying over 5000yen (or something like that). I feel less upset about missing out that one, now that Hasbro is releasing an all new mould red Rampage.

Slightly off topic. The 3rd wave of TF EZ Collection in Japan will include the 4 Animated Legends moulds, as well as Arcee, Jolt and repaints of movie OP and BB again. Not sure what the repaint of BB will be like, but the repaint of OP this time is just the normal ROTF Legends OP but with all the grey plastics replaced by clear plastics.
