Parks will still build them, just smaller, more economical for each park. Though they are running out of space, Hersheypark is up to eleven, and does not build monster coasters, but people still come
A: In all of the Paramount parks, the emphasis was on wooden coasters, and they put in some great wooden coasters."
Well, this sure isn't the case in Santa Clara, where the one woodie was an awful coaster from the beginning. I worked there the year it opened, and was able to ride before the public. Inexcusable with one of the best just over the hill in Santa Cruz. But if he wants to turn Gt America into a great coaster park, no objection from me. If they're good, they can be big or small. It's the closest to home, but not worth going more than once a year when we get in free with the wife's company at this point. Realistically, though, I don't see anything major happening here until the thing with the 49ers plays out. Cedar Fair is hinting they'd be willing to sell to the team, city says they can build a stadium without CF's approval if they replace the parking spots elsewhere, so right now it's a bunch of peacocks preening and strutting.
From an entertainment standpoint, I could care less if a ride is the tallest or fastest as it's just like everything else. Someone will always make something better, faster, or taller in the future.
What it comes down to is if a ride is fun regardless if it's tall or fast. Think Space Mountain or Spider-Man.
But I understand that each park wants some sort of visibility on the map by having the fastest or tallest of whatever type of ride. I just think Fun factor is more long-term oriented, while height and speed are just thinking about "now".
