Exactly! Just rode it yesterday, and it was intense. If the ride was longer the "novelty" would wear off, and it wouldn't be as good of a ride. Sometimes, the longer a coaster gets, the worse it gets. I see no point for a designer to make a ride long just for it to be long and have the overall ride experience hurt in the process.
Anyways, Only a few more hours 'til the announcement! Can't wait for this one!
