Dunno if its been posted already but I was pleased to see Burry Stander on a 29er podium at the Worlds today.
Burry Stander of South Africa was riding a Specialized HT. He's not a very tall rider compared to some of the others so the larger wheels were quite noticeable. At least one American was riding a 29er as well.
I also noticed quite a few tubular wheelsets. I think they were Geax tires (tan sidewalls) and Edge rims. Most of the Swiss riders were setup that way. LOTS of carbon frames, and HT compromised ~90% of the bikes in the race.
