Here is some Transformers news that didn't come out of Botcon, but it did come out of Japan-- more specifically from Medicom's toy showing.
Here, Medicom mixes their popular Be@brick line with Takara's Transformers-- and the cool part?-- they actually transform!
Included in the first series are Optimus Prime, Megatron, Bumblebee and Starscream.
I'm not sure if these will be available outside of Japan, so until we hear otherwise, you might have to check your favorite import toys site to add them to your collection. Although, honestly, I expect them to go up for sale on BBTS any day now. They seem to get everything.
