This topic comes up every July and the same debate happens.
I expect that Disney will raise their prices, however, what is more bothersome to me is how their increases have far exceeded the rate of inflation.
As most of us are taking steps backwards in standard of living for a variety of reasons (job loss, no increase, increases less than the rate of inflation, increased base living costs such as healthcare and other insurance, etc.), Disney continues to price increase well above normal levels.
Essentially, they're slowly pricing groups of people (classes if you want to call it that) out over time. If I continue to earn at the rate of inflation and get increases such that I maintain my standard of living, but do not beat inflation - I will be priced out of Disney at some point.
I don't look at it as this year Disney raised prices and they've impacted their attendance draw because those impacted by the recession can't go. I look at it as, over the long-term, they're pricing entire wage categories out because their pricing is moving faster than those earners are moving.
It means:
1) More people visit less frequently (annual quests to bi-annual, etc.)
2) More people just don't go
I equate it to climatic change vs. seasonal weather effect if you want a comparison.
Even the new park openings don't account for the huge increases in price over time because you can see the trend 1999-Present. There's tons of data, charts and graphs on this out there. I'm sure some may sneak in here.
