Suspended Andrew, I would like to disagree with your statement about little kids getting bored of it. While I haven't yet made the trek out to Knott's (and after looking at Xcelerator's renderings I really want to) I have been to Knott's Camp Snoopy in the Mall of America. The park features a coaster that looks similar in intensity to Jaguar and my brother who's in 4th grade loves it.
Coasters like Jaguar and Ripsaw (the coaster at Knott's Camp Snoopy) I think are made for people who like coasters, just not ones that go really fast or really high. I don't know if that made any sense, but I hope you see the point I'm trying to get at.

Just wait till next year!
