If Test Track's update succeeds at making it a great attraction again (which I hope and cautiously expect to happen), Future World (sorry, I mean World Discovery + World Celebration + World Nature) will be incredibly lopsided. The only big draw in Future World West (ok not sorry) will be Soarin'. Apart from the obvious benefits of upgrading JII and/or The Seas once TT is back, as Tom Bricker wrote in his recent "EPCOT Wish List" article,
The Land deserves an aesthetic upgrade so it doesn't look like a mall food court. Indeed, if there's one change I'd want to see at EPCOT right now, it would be making The Land feel like someplace special again...
It'll be fine once they put the fossil replicas from Dinoland in there.
