Peabody hit it right on the head, although I always think of it as beemer hyper rolling stock that has OTSR's and one less row. I think the stock is great. You feel the ride sensations more when your feet don't touch the ground, and SDC probably saved a bundle by using this rolling stock as opposed to the floorless, which would have required the special loading platform.
I do have a question, and maybe someone can provide a definitive answer. Does the floorless design slow down loading significantly enough to effect capacity? I have ridden Kraken, but I cannot recall how much of an effect waiting for the platform to retract/restore itself had.

According to the "official" count, next year's new coaster lineup will feature 17 Arrow 4-Ds, 21 TA2Ks, 34 B&M floorless's, 17 Intamin Gigas, 12 beemer flyers, and 247 CCIs. And oh yeah, CP will receive one of all of these.
