This engine is said to be based on the S63, being basically a S63 minus two cylinders.
Any thoughts or comments?

Sure south, I have a thought.
Why not just destroke and/or debore the S63 to 3.3L (or whatever) and use that in the M3 instead. Sure it is a bigger package, but who cares? The next 3 series chassis is very unlikely to get smaller (though it will likely be lighter) so a V8 will still fit I'm sure. If they want lower weight then they should look at employing the magnesium block for the turbo motors, including the V8s. I am sure it is technically feasible, it just needs more R&D. Don't waste that money on a new V6.
Alternatively, they'll have a successor to the N54 ready for the next 3 series so that too could form the basis on an M motor.
It does not seem worth the development effort to go with the V6.
