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
