In all the various forms we've witnessed for the potential future of EPCOT, the one thing that seems to be clear, is that they are addressing the countless issues raised by guests that have been stated here as well. Those issues being related to the heat, patch work "updates", and empty shells of attractions.
We see the current announcements bringing more to do for families in the form of more IP attractions. Yes friends, like it or not, IPs like the dreaded Frozen or more aligned Ratatouille are great for families and the modern park guest. So long as they maintain the majority of the World Showcase values, I can certainly welcome some of the IPs to provide family fun and refuge from the weather.
The varying blue sky art always lends itself to what Marni has hinted at or stated when possible. That's the spine re-do is bringing a more modern look, not in the form of Blade Runner-esque architecture, but in the form of openness, greenery, water, and depending on your viewpoint, elegance. There has been so much discussion over the years about the heat in the tombstone entry and the heat in the "Dutch oven" by communicore with the buildings tightly surrounding the vast sprawl of concrete. Only my opinion, but I think moving toward the wide paths, trees, water, and smaller independent buildings for shops and dining options is the way to go. (Not too mention if gives them more practical real estate for the Food & Wine carts which is really driving their revenue stream.)
