It's painfully easy to make numbers on a dial- give it a big bore to stroke ratio and voila, you're there. That 9000 rpm V8 you want (100 hp per liter)- they could have done that 15 years ago with one eye closed (95mm bore, 80 mm stroke, done).
Designing a motor that's compact, powerful, responsive and efficient? That's a worthy challenge.

I don't think he means "let's make it 9k rpm, we don't care what ever the cost is". AFAIK, the point of M engines are they're high revving AND have flat torque curve AND as a result have their max power at (or close to) red line AND they're not terribly inefficient. So when we say next engine should be 9k rpm (or something more than 8.4k rpm) that doesn't mean make it no torque at the low end and have a 10mpg on the freeway...
