Haven't heard anything yet.
For quite a few years, they raised prices in the spring, instead of January, and we always thought it was odd to raise prices at one of the busiest times. Since it hasn't been six months since the last increase, maybe they are going to start doing that again. Just a guess on my part though - nothing to back it up. I'm hoping that since Universal and Sea World have also recently changed prices, that they'll all hold off a little while.
However, if you know you are going and can afford to buy tickets now, I would. I doubt very much that they would go DOWN in price between now and your trip!
