I've had similar longevity from both 105 and Ultegra hubs in the past so it's not just Dura Ace that tolerates this maintenance schedule.
Use good grease and lots of it. The excess grease doesn't contribute to the lubrication but does act as a seal to keep the hubs clean inside. Plan on wiping the excess off the hubs after the first couple of rides.
I'll echo that for shimano hubs; I put 50,000 miles/year on my commuter and repack the hubs twice a year. Also have a set of Rolf Vector wheels- the ones with bearings/cones, not sealed- that have at least 100,000 all weather miles on them and are still in great shape.
