How do you get around the fact that 4 doesn't divide 6 evenly, i.e., 6 cylinders and essentially 4 turbos. You can't just put 3 cylinders on a twin scroll unless you are alternating which port the cylinders are feeding. (And I think even the folks at M might think that's a bit of over-engineering.). Otherwise you'll have two cylinders feeding one of the "scrolls" but only one cylinder feeding the other, resulting in an imbalance in the pressures within the turbo.

Based on this, I think a three conventional turbo is more feasible, and therefore more likely, on a six cylinder engine.
