I did, and Duane said to me that he doesn't want to presume that the ride works the same as SFDK's Skywarp, so he's waiting until he sees Skyline at a conference in a month's time until he decides whether or not to put it on the database. That's what he said to me when I contacted him, anyway.
None of the skywarp derivatives coast at all. Each set of coaches is connected by a series of skeleton chassis to maintain distance and there are tire drives in each station. Either one or both tire drives are engaged at any given moment.
One can count coasters however they want. I personally won't be counting these skywarps due to the powered aspect, but some people might want to because of how much they resemble a true roller coaster, which is understandable. Ultimately, it's your own coaster count - you can tailor your own rules however you want.
Fair enough; I will personally be counting these Skywarps because RCDB has Harley Quinn on the database and because the system behind these looks more like that of a coaster than that of a super loop. To me, it's kind of like the difference between a half-pipe and a Disk'O.
