I think advanced haptic feedback is still pretty far out. None of the companies working on headsets seem to be focusing on it at all, and you won't see it really take off until something like that happens. There's already some basic things out like the bHaptics stuff though, so hopefully I'm wrong.
As far as headsets go, you could keep your eyes out for the Reverb G2 in a couple of months since that might be good. Other than that, the only good option is the Index if you don't want a Facebook headset.
