Most modern motors are synthetic ready - except those that contain plasma moly or chrome rings, and those that are rebuilds. A new engine has, despite vastly improved production methods, clearance variances and will be tighter than a broken-in motor. Some of the new parts also need to relax into somewhat. After 600 miles or so, most of the metal particles that break-in causes have ended up in the oil. I'd trust a good filter on catching any big-enough partcicles that would otherwise be of concern. Seating the rings is extremely important. The method of "throttling" a new engine has been described just yesterday in some other thread. You want to establish an even wear pattern. On a new engine, the rings seat very tightly, and combustion contamination of the crakcase oil is less of an issue. I would go with the manufacturer's recommendation regarding the first oil change. Audi recommended the first oil change on my '96 A4 after 5000k miles, too.
