I do know think Nexus angle has been mess up at all, I think WWE is handling it the right way because if you let this Nexus angle get out of control you will find yourself with a version of the NWO and I think the WWE wants to stay away from the deathtrap happening with Nexus.
I believe that they are playing it right and they are letting it go they way it should go beside they added Cena and two other superstars to the ranks, I think this Nexus angle will go on past Survivor Series and maybe until WrestleMania that is what I am think but you never know with Vince and writers, they could kill Nexus off tonight for all we know.
