If the gen to come is to utilize bigger turbos pursuing high end at cost of low end reponsiveness that N54/55 is good at, which is most likely the case, it's not worth the wait at all.

Nobody is going to be fine with a lighter and less powerful M5.
It's not "theory" that a straight six can have three turbos...
