*checks for Optibotimus video review. nope. leaves*
Also, i don't know what TFW is talking about. Prime isn't the end of their line. So far it's Bumblebee, Megatron (due out i believe around Christmas time), Optimus Prime, which i think is scheduled for early 2016 and they've shown off at toy shows Starscream. I think if the demand is there, they will continue but they are limited to only the Dark of the Moon license, as TFW did say though.
