Personally, I think it's just another gimmick. It looks sweet, and would attract tons of attention, however, if you look at the big picture... this is just another element in an otherwise standard steel looping coaster.
As far as I can see, this tilt element only happens after the initial lift hill. After that is done, it's all just like any other steel coaster. Loop here, corkscrew there, back to the station. If it had another tilt element further on in the coaster's run, or another original new feature yet not used in today's coasters, then it would be something to behold.
But for now, that's only a new feature on an old idea.
I think Arrow's new coaster design will best this. Don't get me wrong. This feature looks great, and adds a real "thrill" factor. However, the lasting impressions will be something that is entirely new (not just a single feature), and that lies in Arrow's new coaster!
