I don't know if you own one, but I don't think this will hold true. The true M cars are just so much better in a way that can't be explained on paper. It's about the feel and the responsiveness they have. Way better suspension, better engine response, faster steering, LSD. The argument for the longest time was that the 335i / turbo cars were better for daily driving because of low-end torque, personally I haven't noticed it. Actually the opposite. My M3 is so much more solid and comfortable than my 335i was. All of them are turbocharged anyways now.

But yes, coupes, RWD, manuals are dying. Chris Harris was #savethemanual for the longest time, until recently where it's shifted to save driving as we know it. Electric cars that drive themselves and 2.0t will be in good supply.
