Is the 3-day seminar dead?

I've been waiting for the next Denver seminar to get posted and now it has been(yay!) however I noticed it's a two day event.  Are all seminars two day events now?  Also, how often is the Denver seminar going to be taking place?

 Yes, all events are 2 days now so they were able to compress the 3rd 1/2 day into 2 days with better organization and time management besides the breakout groups.

Thank you.
