I think no matter how you do it your gonna have a mess of supports with this kind of coaster. X already had a crap load. A couple more probably wont make much of a difference.
As for what the ride does overall, since everyone else is giving their opinions, I'll give mine. Kind of a mix of whats logical and what would be cool. I'm gonna agree with the 180 right turn out of the station, lift hill, drop to bottom of the Raven turn that is being constructed. If the exit of the first raven turn does end up being Immelman-like, then the track should be in a standard coaster position for the rest of the ride. It goes trough the zero-g-flip-thingy and luge turn like X only the train will be upright. I doubt it would do all this with the seats backwards. It might, but I think its going to face forwards when not inverted (meaning facing foward up the lift and down the drop still doing a flip ant the bottom) as opposed to X. The footers look like they come back around the station and back towards where the crain on the left is. If you look, it looks like it is siting on a very large footer parhaps for a second raven turn similar to X's. Then it will go back into the station. The other elements, if any, I don't think anyone can tell. I would assume a half-half or full-full before the second raven turn meaning it could be either an inside or outside raven turn with either a half-half into the brakes or just brakes after the turn. It will be interesting to see what actually happens.
