Dark Knight Coaster had started its construction, but in the state of mass, there are mandates for these enclosed buildings. These buildings however have to meet certain criteria similar to that of an office building. As you can imagine that will drive the cost way up. Six flags wasn't allowed to just erect a building, the building the had to have the same building requirements as that of family dwelling or office building which would drive cost way above the other 2 installations. Basically... don't expect any NEW indoor coasters or rides to be installed in Massachusetts. So yes, this ride will be completely outdoors.
