It sounds like the Supra GRMN / Gazoo or whatever you want to call it, is the top of the line model that will be release at a later date. I still expect the base model with the 385hp B58 to be release sometime late next year.
Could happen.

Well the concept didn't really have much of headrest for the backseats either.
Good to hear, because if they try to sale a 250hp 4 cyl model in the US for $50k it would be a laughing stock and just collect dust at the dealerships.
