The prices for resale are going up and will continue to go up. Someone said, "If you see a price for ANYTHING at Disney, whether it is food, tickets or lodging, then BUY IT, because that is the lowest price you will see for the rest of you life. It WILL only go up from there." (DVC resale might go up or down a bit, but the general trend will still, always be up, because that is how Disney does things.)
First of all, Disney is pulling prices up by taking so many contracts off the lower end, with ROFR.
Second, Disney raised the bar when they raised their prices for DVC, and most especially the 3 highest priced properties. The effect of that is still percolating down through the system, and it continues to pull all prices for resale up.
I read an article that said Disney had raised their prices this year, in order to prepare for even higher prices in the future, and they said that it was a gamble on the part of Disney. Too much of a price increase (which a lot of people think applies to Grand Californian, VGF, and Poly) and you drive away your customers. Not enough and you leave money on the table. The article felt that Disney was gambling with their high prices, because if the economy turned down, things would crash, and Disney WILL NOT want to lower them. I actually think the article was wrong. I don't think Disney is gambling at all. By raising the top 3 properties so much, they essentially shut off their market in those properties, but there wasn't that much of a market for them anyway. Meanwhile Disney has continued to be active and healthy in the Resale market, and those lower end properties are priced low enough that they will continue to sell, even if there is an economic downturn, especially because they are 'such a deal' compared to the higher properties.
Anyway, the point of all of this is, that for at least the near future, the price trend should be up, in general, so waiting to buy will probably be a mistake.
