Frankly, I consider that unacceptable given its power output, down ~20% in hp and ~30% in torque to both engines. No, I don't care about HP/liter and neither should you. It's not like there are engine displacement restrictions for production cars. Why confine yourself to unnecessary boundaries? I don't see the benefit of sticking to a certain philosophy if it doesn't produce competitive results. I like BMW's decision to switch to forced induction. It shows that they are willing to change with the industry. I would be concerned if they decided to stick with their current formula of high revving engines because it's not appropriate for the current market. The next generation of M cars are going to be lighter, more powerful and consume less fuel than the current generation. How can you complain about that?

You realize the V8 is lighter than the 6 cylinder it replaced don't you? You realize neither of those v8's you mentioned has individual throttle bodies, right?
You don't care about hp per liter? Ok, so BMW should just stick in a 427 cubic inch V8 and call it a day? The hp per liter is what gives the motor its characterists, by design it has to rev higher.
I don't think you get it, competitive results? BMW is competitive, actually best in class, with smaller engines. The M5 does not need 6.2 liters to beat the benz V8. It does need its redline though. This is also what makes it special. The only other motors that are anywhere near as special as the S65 or S85 would be the F430 V8 and the GT3's flat six. That is it, and BMW offers the best motors for the money of these manufactuers. Sounds to me like they are doing fine, some people just don't get it and never will.
Say what you will about forced induction, I don't think the M3 would give me as big of a smile if it wasn't screaming toward redline.
A 911 GT3 would just turn into... a turbo.
An F430 would no longer have that special ferrari high rpm wail that makes your spine tingle and is an intrinsic part of the driving experience. Yes, the motors are less fuel efficient, yes, they don't make as much torque, yes, they are freaking special and unlike anything else and therefore worth their premium.
