Here is a summary of a more detailed write-up at http://blog.skilodgingrental.com/2011/03/14/vail-resorts-epic-season-pass-on-sale-through-53011.aspx
VR has renamed the Colorado Pass to the Epic Local Pass and made it available online, even to first time purchasers. It now includes Heavenly and Northstar with the same 11 blackout days (up from 9 this year) as the 10 days at Vail and Beaver.
The Keystone/A-basin & Summit pass have sorta been merged into the Summit Value Pass with the same 11 blackout days at Breck.
They also have a Tahoe Value Pass with the same blackout days, but no Saturday access at Northstar.
Spring benefits look similar to last year with prices about $50 higher for the Epic & Epic local pass. The 4 buddy tixs are now $69 in CO and $60 in Tahoe with floating prices for the 6 ski with friends tickets.
