Definitely. It's kind of like how Nissan has the new Skyline GT-R named just GT-R. I think it's smart that Lexus is doing it, it'll most likely be a high performing car with a luxurious side as well.
I believe there is a site out there confirming that is the new supra (or the concept) and there are rumours of a v8 or a v10 powerplant. I am going to try and find the site again.
That's a pretty mean looking sucker. Hopefully we'll have a new bunh of cars to harass and aim for soon. There's really nothing out there to shoot for but the Z06 right now.
