You should be more than happy. FYI, Ratatouille does have moving eye point also known as parallax, when the RVs enter and leave the room the video adjusts to compensate. As does Shanghai's Pirates. This ride will be no exception. In fact, they've really taken the parallax tech to the next level with this ride with some really innovative AI.
Ratatouille has some basic effects as you enter and leave some rooms, but definitely not moving points of convergence, because there are multiple points of convergence, since there are multiple ride vehicles in front of the same screen.
NOt sure about shanghai, as I haven't ridden it, but I understand it as having huge screens that are more like simulator screens, so again, not really moving points of convergence.
This ride SHOULD have better tech, although the HD version of Spider-man isn't too old, so I'll be very impressed if it is a step above that. To me, it HAS to be, or Disney has completely lost its mojo. They know Universal has taken them to the woodshed, which is why there is such unprecedented ride construction going on now. They have to show they are ready to play ball. A Ratatouille clone and a clone of a very poorly themed TRON coaster that has essentially no TRON theming don't bode well.
I expect this ride to use the same tech as SHanghai Pirates for the screens. Which apparently is a good thing, and the only real modern masterpiece Disney has made. Mixed in with some Mystic Manor effects, and it should be a great ride. One with a 4 hour line for a year or more, yay!
Remember when Universal was horrible for being all screens. Wait, that's still what people say.
