Disney doesn't really have a screenz issue that can't be rectified. It's pretty much DHS that is becoming a bit too screen-centric. Some people will argue Epcot has a problem, but I just don't see it when I visit. Most rides are practical based (although if they'd like to replace M:S, I say go for it).
I should clarify that I personally don't think "screenz" are a problem. My issue isn't with screens themselves. it's when you have too many of the same attraction in one park. Simulators cause this problem the easiest because you're just sitting in front of a screen (or moving in front of a bunch of screens), so it makes the experience feel a bit same-y. But just using screens is not an issue. It's more how they are used than anything.
