My thoughts:
1) There will be good deals in the future.
2) Prices, even with good deals will be higher in the future.
If you think you will buy eventually, the question is why are you waiting? If you are waiting because you don't have all your finances in gear and are waiting to pay off your new kitchen before anyother big purchase (or something), then you should wait. If you are waiting because you aren't 100% convinced SSR is for you and want to see the details on AKLV or other future resorts, then you might as well wait.
But if you are just waiting because you've got some other things going on right now and don't want to deal at the moment, then get your act in gear and go buy!
