Pretty sure it will be a 8cyl TT putting out less than the nextgen M5 version.
It is pretty well known it will be a 6 cylinder.
My best guess is it will be around the 4.1-4.3 0-60 times. I highly doubt the BMW published value for it will break 4.0. Even though it would be lighter and up on power (and torque hopefully), I don't see it being in the 3's.
Who knows... maybe they will offer a tuned and dieted M3 like a true CSL should be.
