You are on to something there...
The other thing to consider is that the M5 has been repositioned in the sense that it is now larger and more luxurious than ever before. M said they would not make an M7 (M Performance is coming BTW) because it is too large to be a true track car but with the F10 that is really what they have done.
That said, the M3 is what they race, the M3 is what is positioned against the true sports cars so it may be in Ms marketing decisions to reposition the M3 (and if you read what they are saying about it being their "performance halo") as the model they no longer hold back on.
I've been told that the new F80 is a game changer on many levels. The M3 CRT was a hint at the future with its 450hp and 150lbs less weight yielding an impressive 7.7lbs/hp. That seems like a nice round number
