Personally, I would agree with the idea of it being dated. When the show started, the idea of that globe-shaped screen that only showed video over the land masses seemed like a huge technical innovation over the metal ball they projected lasers onto.
Today, I notice how difficult it can be to figure out what's going on in some of those small areas to people who haven't seen it dozens of times and it seems like it should be the whole ball capable of displaying stuff and not just those areas... but making a change like that, aside from costing money on new hardware would, I assume, require them to redo the movie since those clips were easily repeatable across the globe thanks to the edges created by those land masses.
Also, as someone else mentioned, that show was introduced at a time when they weren't hiding so much of the waterfront from view around world showcase and weren't making viewing from some of the only truly good places left a fastpass or upcharge spot.
There are other small things, obviously, but I think a lot of the problems with ROE could have been addressed over the years by making appropriate technical updates to the existing show (and putting a little more long-term thought into that waterfront area) but we all know that's not how they roll.
Unless it's a big enough change for them to do a marketing blitz with, it seems that modernizing anything to keep up with the times is heresy.
