I have many fond memories spent in that Tomorrowland, but please no.
I'd just as well make Fantasyland look like this again:

And to those thinking, "Um, yeah!" let me just say your lens of nostalgia is so thick that it's apparently opaque.
I'll wait and see what we actually end up with, but sterile, sleek and clean isn't a theme (though it could certainly be an aspect of one.) Without the spires it's really just a nice plaza.
I've said it multiple times now, but Tomorrowland's biggest problem is it's never treated like an actual land. Instead it's always more of a design aesthetic. The 90's redo was a step in the right direction, but never seemed fully thought out (or even completed) and sat as more a simple redress.
Where are we?
When are we?
What's the history of this place?
Who lives or works here?
Storytelling, theme, character, and craftsmanship. Give me the Disney difference. Missteps have certainly been made, but steps backward are worse- it's not learning from your mistakes, it's giving up.
