I just read over on the main trip planning board that there is a ticket price increase expected on the 19th March...so if you're planning on buying in advance soon- buy 'em now!
I hadn't heard of a recent price increase at WDW, maybe it was Universal or SW? I don't know, but on the main TP Board, there was no mention of 'again' only that the tickets were expected to go up - I'll see if I can find out more...
