My Magic 8 Ball says Chances Are Good the promo will be extended & offered again in 2011...maybe at the "normal" time in the Spring.
I seriously doubt that they filled the rooms with the early promotion for next year. I didn't book until Sunday--the day before the promo ended--and had no trouble getting my choice of resorts...and room variations were all available. I looked at several mods, a value, and a couple of deluxes. Had my choice of standard/preferred/view, etc. at 6 different resorts. Booked two rooms at POFQ, no problem. Looked to me like they had plenty of rooms left...even starting on Labor Day weekend.
