If you feel the engine is just a mildly reworked 335i engine you should read this thread: http://f80.bimmerpost.com/forums/sho...d.php?t=893611

If info is correct, we are looking at a engine with different bore spacing (meaning a very extensive retooling process), a oversquare bore/stroke, and a completely new block (as can be seen in the pictures in the thread I linked to above).

It doesn't share any parts with the N55 apart from ancilliaries. New block, new cyl head and internals, new rotating assembly etc.

To me, that is sufficient to say that the S55 is a dedicated M engine (again, based on current info).
