I don't think this will be the monumental improvement in performance we got with the E36->E46 or with the E39->E60.
This is why the tunability of this car is so important to me. If I can't extract significant gains out of this engine with a tune it's just going to be really hard for me to sign the dotted line at the dealership. For $70k+ I expect a car that is as fast as a Mustang GT or a base 911 and nearly as fast as a base Corvette, but with additional luxury and style. Otherwise, I will look for two cars(my DD beater + Corvette) to offer what I hope to find in a single one (M3).

I raced a 2012 Mustang 5.0 GT FBO and versus my E92 M3 FBO and the mustang pulled 2 cars on me. I then removed my front seat, rear seats and trunk mats (approx. 115lb total) and race again and pulled half a car on the Mustang consistently.
Do not underestimate the performance advantages of lightweight. At 175lbs lighter than E92 M3, +100-lbft of torque all across the powerband and at least +30-40whp over the E92 M3 (I would be surprised if the F80 dynos less than 380whp) the F80 will have a monumental performance improvement over the E92 M3.
