I got the same dates, it is a contest to win a trip to the Press Event for the opening and states must travel 4/6-8/05. So no soft opening dates, but I feel those must be firm dates.
There is currently no confirmed date for soft opening, or official opening.
8 November 2005: Expedition Everest Grand Opening Press Event
According to a contest being ran at The Daily Buzz, Expedition Everest will be holding a grand opening press event on April 6 - April 8 (note the dates remain tentative). http://www.dailybuzz.tv/disney/rules.php
30 October 2005: Opening team recruitment underway
Disney will be recruiting the opening team cast members in mid-November 2005. The opening team will be responsible for cycling the attraction during the test and adjust period, and preparing for operational duties once Imagineering hand over the attraction. The assignment of an opening team is one of the major steps needed prior to any soft openings. The latest information seems to suggest that WDI and the opening team may be riding in December 2005, with an outside chance of guest testing in December 2005, with more wide-scale soft openings taking place in January 2006, leading to a full official opening in Spring 2006.
June 2005
Official information lists Expedition Everest of opening early 2006. With such a long construction phase, it is difficult to predict ahead of time exact opening dates. There have been some suggestions from people working on the project of an outside chance of some kind of soft (testing) opening in January 2006, although none of this is officially confirmed.
