No news is good news for touring hubs as far as I'm concerned. They've been out for a few years now, and if theses things were failing we would have heard about it.
I was in basically the same market for hubs as you last year, replacing a set of shimano's for no other reason than aesthetics if I'm being honest with myself. Had it narrowed down to WI, Royce and VO before a VO 20% off flash sale convinced me to pull the trigger on the Grand Cru's. I've since met one other guy who is a very discerning high-mileage randonneur who has also been very happy with the hubs.
