Not to be annoying, but I'm STILL so perplexed:  we never confirmed a definitive "why" regarding this whole track replacement situation.  I mean, really, this is quite unheard of.
So what was it? Simply proactive safety?  Were there structural problems?  The sound issue?
Universal wouldn't spend millions to effing re-build a coaster from scratch, only for a slightly smoother ride with updated vehicles, IMHO.
Please only comment if you know the actual reason... we've already speculated to death
