After watching the video:

I give it an 8 out of 10. (But Expo, you're a Fanboy, how can you?)
The narration, I'm sure can and will be tweaked. They did it to Dame Judi with SSE. They can easily alter the man's voice to make it slower and deep and add in or take out various parts of his script. There were parts of Dame Judi's script that were later added to SSE.
There are only 4 character speils, and only the last two are lengthy with Buzz and Rozz. I really enjoy the female voice for the Space Mountain refurb speil, honestly, I would rather have her narrate the entire TTA speil than the guy who's doing it now.
Yes it's a little ORAC-1....but they can add the TTA arrival jingle each time we reach a destination, just before the man narrates, and they can add in Mr. Johnson's speil as well while passing the speedway along with the female space mountain voice doing the "TTA services all of..." etc
There ride is refered to as both the PeopleMover and Tomorrowland Transit Authority PeopleMover, the TTA wishes that you have a great big beautiful tomorrow and the Carousel of Progress gets a very nice description and the model city is once again called Progress City and there is the "Experimental Prototype Community of Tomorrow" reference.
Other than the brief character speils (ummmm C3PO and Master Computer from Disneyland's PeopleMover anyone?) and some irks with the man's voice, the new speil isn't that bad to me.
