The M3 is getting canned because this generation sedan ends production, as simple as that. No more F30/F80 after October, enter the new G20 generation.
The next generation 6 cyl M engine (S48?) is not yet ready and will debut in the new X3M, so the S55 it is for the updated M2. Not necessarily a cost cutting measure since it is more costly to produce than say, the N55.
