To all the nay-sayers:
Lets be real, it's been a long time since M has been about light-weight purist-oriented products (I'm looking at you X5M). 6-speed manuals and high revs have been getting phased out for years now. In the GT-car age of today's BMW, I'd welcome the effortless torque that the AMG philosophy might bring.
Lets also not forget that while we've all been clamoring for an M halo car, AMG has come out with many compelling products that BMW can't match. SLR, SLS, the black series range... I'd like to see some of that from BMW too
