I think comparing the proposed 94 upgrade to Horizons & an upgrade to Peter Pan, Space Mountain or Pirates is crazy. I can say that I rode Horizions back in the heyday; I remember the ride & I loved it. But looking back objectively, if I rode it now, I would complain how outdated & ridiculous it was. No matter what upgrades were made to the original ride, it would always be somewhat outdated. Look at the criticisms of MK's tomorrowland. Unless there was an unlimited source of funds (and even Disney has their limit), Disney would never be able to stay on the cutting edge envelope. As soon as a new idea came about, after the design & construction, by the time a "futuristic" addition or change got added, it would be out of date. I agree it was right to pull the plug on Horizions. I guess I'm in the minority in that I really like MS. (Although I do agree that orange has been calmed down - I swear it was more intense when I rode it during soft openings in July 2003.) There are some rides based on "classic" Disney stories / movies that will always be classics. That doesn't mean they can't be polished up & reburished, but some things will always be classic.
I don't always agree when WDW screws with attractions. I liked Alien Encounter; and even though I actually like Stitch (yes, I know it's a sin to admit this here), I think it was a horrible decision to make AE into a Stitch attraction. I am probably in the minority that I don't like the Johnny Depp figures in POC. Don't get me wrong, the figures are awesome looking, but up against the old figures, it doesn't work to me. Seeing a handful of 2006 new awesome animatronics against the ones from the early to mid 70's doesn't exactly work. It's still a great attraction, but I think I enjoyed it more when I rode it in the late 80's & early 90's. (Update more of the existing figures and I would probably change my mind here. I know giving even half of the existing animatronic figures updates would cost a fortune, but it would make the ride much better. I know this won't happen.) I still mourn Mr. Toad's Wild Ride leaving WDW. I've never been a fan of Space Mountain as I don't like roller coasters. I also got stuck on SM when the lights were on back in 1989 & after getting good look at the ride, I choose not to ride it anymore. DH loves it so I go & play video games in the aracde while he rides. He hasn't ridden since the newest changes, so I can't comment on the new elements.
Other decisions, I like. I like Soarin'; I like MS; I like the upgrades to HM. I am hopeful for the new Star Tours. Upgrades are necessary to keep things fresh. I think Epcot would benefit with some other upgrades - for example, either update WOL or tear it down & re-do it. (Using the pavilion for the festival center for F&G and F&W is sad.)
I know this post will irritate a bunch of people & I'm sorry. I generally lurk & post infrenquently, but I felt like I had to speak up. Flame away.
