I think it would be pretty easy to work out the peak horsepower for the new car if they leak a peak rpm...considering they've already said peak torque is around 395lb/ft.... and we could probably assume the power curve will pretty much match the F10 M5... I just chucked the numbers into excel... the numbers in bold suggest are the suggested outputs assuming an M5-esque curve... It seems pretty obvious bmw would have purposely detuned top end if output is much below 450bhp...and M cars are meant to be all about top end power...so Id imagine they dont want to destroy their brand image too much. Sorry for the bad dodgy excel format
