C'mon man....you really think half of those rides warranted a "price increase". Even if you enjoyed those additions, they weren't bringing anyone in as attendance was at a lull for most of the 2000's (removing 9/11 and the economic crisis, of course). The reason the "dark ages" are discussed around these boards because it was true. Costs were cut and you could see it at both parks (Brown hulk, no more fire at Jaws, broken effects around both parks). Hell, the only reason Dueling Dragons was painted was because they didn't want JK Rowling to get a bad impression of the Potter's future site.
Furthermore, that list you provided are mostly additions (replacements) to USF.
As far as what has Disney added/gonna add:
Big Thunder Major Refurb
Storybook Circus
Test Track (set for late 2012)
Sorcerors of the Magic Kingdom Interactive game (hey, it's part of the theme park experience)
Surely if you justify Mat Hoffman and FF Live as a reason to increase ticket prices, then you surely must agree that Disney has added something this year.
