They really have no choice IMO, from a marketing perspective at least, unless they want to let FOX walk away with the game. I would expect the new Charger damper and black stanchion treatment at the very least. Not sure how much further the weight can go down without resorting to exotic materials, but as it stands now, their traditional weight advantage has evaporated with the release of the Float 40.
Given the massive resources available to SRAM, I think they'll pull something tasty out of the bag for 2014!
