For the first five years, expect long lines. It's like that with every coaster. I don't care if it opens in 2007, the lines will be so long, that I'm probably gonna wait till 2008 to ride it. I did that with ISJT. I went in June in 2005, and at 10, the tickets were are 9 o'clock to ride it.
Sadly, X-Flight has a low riders her hour, but it will, "hopefully" even out.
