It's been pretty clear for a while that it wouldn't be the actual mechanics of the ride system that held things up. They are going to want that wrapped up before the ski season ends. The stations also don't have that much longer to go, maybe two more months. There is still the question of when they will receive the rest of the cars, last we saw there were still only a small number on site.IG work? Not sure what that means.
Blog Mickey had a video of an actual gondola traveling to HS. I think my original assumption is correct. It is not the ride system that is holding up the opening but the construction of the stations.
