If there were still any doubts that Busch Gardens Williamsburg is planning a Premier Rides launched coaster for 2015, this article from BGW Fans should nicely squash them. The website was able to obtain a full set of plans for the ride, showing various details and layouts that leave little left to the imagination.

The Busch Gardens Williamsburg version will feature three car trains according to the documents, increasing capacity a bit. That's still only 18 riders per cycle, so expect a long line for this one. The theme of the ride seems pretty wacky, something along the lines of stunt bicycling in a carnival type atmosphere.
