Rikishi is still in the WWF, if I remember correctly he is in the Raw crew.
BTW, currently HHH's physique ain't quite as great when compared to the one which he returned after his quad injury. He seems to have melted lots of mass and gain more fats. I mean...his Lats, Chest and Arms ain't as huge as it was anymore, but it is easily understandable since he is back in the extremely busy prowrestling life. Just a shame though.
