Disney Blog posted a new video of the progress of the construction.

The attraction will offer an innovative ride system with a train of vehicles that respond to every twist and turn, plus appearances by animated figures from “Snow White and the Seven Dwarfs,” and music from this classic Disney film.

I really am excited for the Mine Train. Judging by the size, I think it will possibly be a short ride, but packed with a punch. The Princess Hall seems to be coming along too. Who knows if the video is recent or they are further along by now.
