Well, the next M3 will use a very heavily modified N55 (S55?) because the N54 is ,as you pointed out, close to it's end of life and the N55 is more efficient.
The M division will extensively rework the N55 before they claim it as a 'performance engine'. The fact that the N54 is a forged engine block probably had something to do with it's selection for the 1M.
