There are two ways I look at this:
On the POSITIVE side, the old narration is from 1994 so it was time for something new. The "Buzz Lightyea" segment always felt tacked on and didn't make any sense since you hear it wayyy before you see the actual ride and I also feel that Disney should make an actually futuristic Tomorrowland rather than a retro one.
On the NEGATIVE side, it adds more charecter tie-ins in the park, it guarentees MILF and Stitch are now going to be here for a looooonnggg time to come, it also breaks up and destroys the 1994 New Tomorrowland theme.
You will remember in my first post in my "All magic kingdom, all the time" thread I reported that WDI was moving towards a new tomorrowland so I guess this is one more step in that direction (the lamp was the first). I just hope they redo the whole land and junk the whole 1950s retro theme since it makes no sense at this point without the TTA, timekeeper, and A.E.. I also really doubt the refurbished space mountain will have any connection the retro tomorrowland and instead represent whatever theme the new new tomorrowland.
It's probably headed in the direction of the original 70s FUTURISTIC tomorrowland which I can't really say is a bad thing.
Also, this new narration seems pretty much identical to what Disneyland's Peoplemover had before it shutdown. Will TTA go back to the original name "Wedway Peoplemover"? Would be interesting since most non-WDW fans refer to it as the peoplemover anyway.
Very mixed fealings but I won't make anymore crazy statements until Space Mountain reopens so we can see what the intent and vision for these projects is
