I've also now confirmed it on the Norwegian Ski Associations (skiforeningen.no) web site -- they've updated their Norwegian-language pages but not yet most of their English pages.
The dates for the DO are
March 16 (Friday) to March 19 (Monday).
Crucial dates are:
On or after Dec. 1 -- reserve your tickets (or if you live in Norway, buy them). The best seats are NOK 300, or about $43-50 depending on exchange rates. Cheaper seats (down to NOK 100) are also available. I will post more later.
Friday, March 16 -- pay for & pick up tickets at the Ski Museum (arrange w/ some else to get them if you won't be there yet)
Sunday, March 18 -- great ski jumping, starts ~ 2 p.m.
We've bought our plane tickets, arriving 3/15, departing 3/20.
