PASS has structured its registrations to give the best deals to those who register the earliest.  The current rate of $1395 expires June 30th.  As Greg pointed out in his blog, community speakers have been announced.  Register for the summit at http://summit2008.sqlpass.org/ now to beat the price increase.  Come to the PASS Community Summit a few days early and participate in the pre-cons too.  SQL Bloggers like Andrew Kelly, Kalen Delaney, and Peter DeBetta are offering pre-cons; check' em out!
