Hmm well I guess this would be as great a time as any to step in say hello and add my two cents.
Now I don't want to say that this is what happening but just kind of an afterthought from the 4 original teaser posters of the new 4D coaster, perhaps S&S are using a vertical left to conserve space and in a move similar to Abismo http://www.rcdb.com/ig3185.htm go straight into inversions (not barrel rolls or anything along those lines)but rather flip the riders seats upside down and have them ride it out until they are right side up at the bottom of the hill. Its not like vertical lifts are really anything brand spanking new to the coaster world, just look at Deja Vu and the aforementioned Abismo.
As for the weight problem/issue mentioned before, I doubt any of us are actual physicists here and we all have our theories about what a launched ride could do to a train with that wing span, but then again why not use a gradually launched lifthill, somewhat similar to Incredible Hulk (hah not really gradual but I think you folks get the drift). The immense strain of a 1-60 mph launch in a couple of seconds on a train that wide is a smaller risk when you increase the speed of a coaster from 1-60 over a longer span of time. But I must go with the nay-sayers, I highly doubt its a launched coaster, but wouldn't it be something if it was?
