Add to ORKGWe propose that the Y(4260) particle recently announced by BaBar is the first orbital excitation of a diquark-antidiquark state ([cs][cbar sbar]). Using parameters recently determined to describe the X(3872) and X(3940) we reproduce well the mass value. A crucial prediction is that Y(4260) should decay predominantly in D_s Dbar_s. The Y(4260) should also be seen in B^{-,0} non-leptonic decays in association with one kaon. We consider the full nonet of related four-quark states and their predicted properties. Finally, we comment on a possible narrow resonance in the same channel
