Do we know if the tech diagram that shows the liquid cooling routing, does in fact show it in it's entirety? I ask, because it seems rather anemic as shown. I know it's a 35/65 % design (liquid to air cooling), but come on, surely there's more to it than one lap around the base of the cylinder. Or are we maybe seeing the result of an internal turf war amongst BMW engineers? Seems to be a somewhat throttled back approach.
The new "water" cooling (hey, it ain't really water) ADDS to the existing oil cooling, it doesn't REPLACE oil cooling. According to the design docs, they use the water cooling for the hottest parts of the engine due to the more efficient thermal transfer properties of glycol vs. oil.
