I talked to someone at Fox about the '14 air spring unit - he told me I would have to order a 140mm unit, which could be reduced down to 130mm, but that's it. If you want 120mm, you would now have to order a specific 120mm air spring. I plan to get the '14 air spring banking on the improvements he described.I remember reading in one thread that the 95c was more XC targeted (mostly because of the reduced weight) and thus the shorter travel setting in the fork.
IIRC the fork can be configured either way, as shipped, on both build kits. If they're still using the same air spring as what shipped in mine in '12 it's a trivial change to make. Does required dropping off the lowers, but not exposing the inside of either the damper or air spring assembly. The newer air spring is more complex to change the travel on, but it is possible.
