Shimano FINALLY changed the hideously ugly and irritating-to-true hub design. People in the bike industry, and R&D groups working for giant component makers, please keep irritating aero, lower rotating mass, hidden nipples that require magnets to move, proprietary spokes that take 6 months to arrive, 500-lb of pneumatic rim tension that can rarely be replicated once a spoke breaks type of wheel designs in the realm of way too expensive to spec on weekend warrior bikes. Just by doing that, you will make the world a better place.
The newly updated hub

"Not surprisingly, the WH-7850-SL wheelset will retain its compatibility with Hutchinson's Road Tubeless system and receives the same updated hub design as the rest of the Dura-Ace family. Gone are the hub-located nipples in favor of a more conventional straight-pull spoke, leaving only nipples at the rim for easier truing. Visually speaking, WH-7850-SL abandons last year's somewhat staid appearance for the more eye-popping red-and-black look of the current XTR wheelset. "
