I belive the frequency of oil changes in the US is more a cultural thing than technical. They're very used to short oil change intervals over there traditionally and they simply don't find the long service intervals here credible.
Personally I've owned a few new cars of various makes and have just followed the manufacturers schedule without problems and none have called for an early oil change when running in. I suspect if there is metal in the oil the suspended particles are smaller than the gap between metal parts that the oil provides. If it was a real issue surely we'd be seeing things like premature big end / cam / turbo failures but those don't seem to be the issue with modern engines.
