What could be Chevrolet Camaro Concept Bumblebee, Lamborghini Aventador LP 700-4 Lockdown, Porsche 911 Carrera RS 3.8 Mirage, and Mercedes-Benz AMG GT R Drift. All of which have been previously released as Hot Wheels vehicles. Judging from listings, it is probably the basic line 1:64 G1 Optimus Prime truck cab as the AOE Evasion mode, and less likely a new release for the Peterbilt 379 or Western Star 5700 editions. Surely, we will hear more about these soon. Stay tuned to Tformers.com for all the updates as they happen.

I was interested until I saw the $80 price tag. There is no legitimate reason for it to be so expensive. Pure price gouging!
Wow another G1 optimus prime nobody wants and with an $80 price tag to boot.
That Optimus, is a literal dream come true... but that price tag is most certainly not.
Never thought I would ever say this, but the Bumblebee actually looks pretty good. As a Transformer and Hot wheel fan, this is actually pretty exciting... but then again, it doesn't transform.
