Fox and Marzocchi are pushing a new front hub through-axle standard, 15mm X 100mm, which has been adopted by Shimano, Mavic, DT and many other hub and wheel makers. It is intended for the cross-country and all-mountain market; 20mm through-axles remain the standard for big-hit forks. Fox claims it is faster than using a 9mm quick-release axle while being stiffer and very light. RockShox and Manitou have not adopted the 15mm standard.
