I just happened to see this on their site. Didn't know that they had any plans, but they are proposing upgrading some lifts, including most notably:

Interesting.....
- Converting Albion Double to a Cabriolet to be used for summer and winter operations (and redundant to the Sunnyside High Speed Triple);
- Proposal for a lift above the Hellgate area for "skier compaction" to reduce avalanche risk;
- Replace Wildcat with a HSQ;
- Possible replacement of the Supreme with a HSQ;
- New lift in the Sugar Bowl to eliminate the East Baldy Traverse from Sugarloaf HSQ to Collins;
- Yurt at the top of Supreme.
