My '09 Moab still has the squared off limb ends, but it does use a "rotocup" rather than the limb "pockets". However, I don't see any reason why the limbs wouldn't work on either bow. (Comparing my 08 Rytera with my 09 Moab) The one thing I'd watch for is on the underside of the limbs. I don't remember for sure, but it seems like the '09's had indents on the underside of the limb to fit pegs that were on the new rotocups.
