Tbh, I wouldn't bet on a broad, sweeping change like Ocarina of Time. Majora's Mask, Wind Waker, and Skyward Sword didn't do much differently at the half way point, and TP involved making a previously performed gameplay change available at any point in time.
Changing the overworld to be filled with technology (assuming it's something along the lines of what you've got in the OP picture) would require an insane amount of work that I seriously doubt any developer would put into a single game.
