The '04 geometry is plenty sharp and it's not definitely the case anyway.
Allegedly what happened was that the '05 bikes were tweaked to US preferences, where the Rocky Ridge and other aggro hardtails were specced more as jump bikes, which meant that what was a very sharp handling bike anyway, felt a bit more like a shopping trolley with the front wheel tucked right under.
I rode this year's bike briefly and it was like the steering had gone from sharp to a bit too sharp. If they do go back to the 04 geometry, it's only a slight change anyway, and it's still very fast steering to the point, on singletrack, where it feels like the front is on the verge of tucking under, but never quite does, so I wouldn't worry too much.
