I'm not sure Disney could pull it off at their current rate of attrition. They may need to have Six Bits from Hoop Dee Do double as a bellman at the Tower of Terror.
I too have now heard rumors that they are not having it this year. Still 2 months away so still holding out hope. Not sure why they wouldn't have this event. It has been our only chance to visit in the past 2 years. Not sure I like the direction WDW is heading with tiered pricing and all of the ticketed events.
