Here's another statement by an Adobe staff member in Adobe's public Support forum for CC which states that the current price at the end of your first year is the price that they are charging right now:
fyi, that information is incorrect (we are working to update the post).
Ill try to be really clear, since there is so much confusion on this. If you join the Photoshop photography program, the monthly price for that program may change in the future (up or down). We don't have plans to change the price, but just like all of our other prices for our services and products, the prices may change in the future.
You are not guaranteed that the price you pay per month will be $9.99 forever. It may go up, it may go down.
Unlike some of our other Creative Cloud promotions, where you get an introductory price for a year, and then after a year, it goes up to the regular price, the price for the photography bundle is the regular price. So, once you have been a member via the Photography program a year, your price does not automatically go up.
Hope that helps clarify things.
