This is my understanding of the situation.
A new lift in Liberty bowl was announced and promoted lightly last season. Late in the season the old gondola jumped the track and has been taken down over the summer. It was not used every day and was not scheduled to be decommissioned this year. The staff that may have been used to install the new lift was occupied removing the old gondola. I don't know if it prevented installing the new lift but surely it was a contributing factor.
I believe a fixed grip chair on the Liberty Bowl side would be a great addition for upper intermediate skiers and would relieve the congestion in the lift line at the tram, but it will probably not happen until the economy improves.
Last week Boyne became the operator of Big Sky and their former lender became the owner. I think the implications of that change are clear and reinforce Rio's observations.
In all fairness to Big Sky I doubt if their financial problems are any greater or less than most other USA ski resorts. It's a bad time to own a ski resort.
The one thing that you don't get at most other resorts is almost unlimited skiing. Good snow and no lift lines mean you better get your legs in shapee before you arrive because you can ski to you drop at Big Sky, with our without another lift.
