Even though this might get threaded in the larger rewards discussion, I thought it was worthy of a new thread. I just got this email from Hilton announcing their move to 10 reward categories, seasonal point variation, and a 5th night free "bone" in the mix. You can find the announcement here: 2013 Program Changes
So before everyone starts bolting for other programs, you might want to wait until the follow the leader syndrome cools down and Starwood and Hyatt announce their devaluation. I do love (not) the marketing spin Hilton puts on their claim that ten categories are necessary to "account for all of the new hotels and resorts that have opened in the past few years." Can't they be more creative than that?
