With that being said, my guess is that the M2 WON'T get the S55...this way BMW can keep costs lower and still have the "upmarket" card to play for the M3/4...

My understanding is that the S55 is a completely different motor from the N55. The IC is in a different location and I believe it has some forged internals and additional oil cooling, etc...
