I've been saying that for so long. It's one of my favorite rides anywhere, and it pains me to hear "ahh geez, laaaame!" Or "wow...they look so fake" every time i ride recently. Look at any old video of the ride, and it's truly amazing how fluid and smooth they used to be and their range of motions! We'll probably get a few enhancements or added effects once JP4 is released, but i unfortunately agree with Adri, i don't see the animatronics being replaced until after Potter. Universal can't afford to close JP down for an extended time with it's low attraction count.
Hopefully in the future....and if it's the near future, I'll be pleasantly surprised.
