Anyone that had the N54 (myself included) would be able to tell you that these engines, while rated the same, were not the same in reality. N54 > N55 and now the N55 is getting long in the tooth.
Plus, generally people want something different (aka special) in an M car.
This was possible with the 1M because the internals started out stronger with the N54 to begin with, and then the M guys made more upgrades.
Similar with the S55 in the new M3/4 - significant changes to the original N55, which would be necessary for those levels of power.
My current N55, while a good engine, seems to run out of breath much sooner than my N54. No one wants that in an M2.
Just my $.02
