Morgan has nothing to do with it: it's the welders hired by Kennywood that will make or break any target date.
Morgan may be involved with the testing, but (unless they screwed up in the design somehow [unlikely]) that shouldn't take a whole long time. A few days, a week at absolute most. Remember, all the mechanical and electrical systems are from the original ride, and are still in operable mode. The chain lift was actually running yesterday. The only thing changed is the "gravity" part... that's why the testing should be minimal compared to an entirely new coaster.

I refuse to add a signature. Damn, too late.
