The scope cut of Avatar is more matted than the academy cut. That is to say that they have the same width, but the academy cut has more height. Even so, I'd normally prefer the scope in 2D.
However, let me use an example from Halo Anniversary for why academy is a better choice for 3D. The cutscene that starts Halo CE (or Anniversary) is matted to a scope aspect for that "film" effect. In one of the shots, the captain of the ship is looking at a holographic projection which is mostly circular and, in 3D, the holgram pops out of the screen. YET it was bound (clipped, cut-off, whathaveyou) by the bars added on for scope aspect. Since the object was "closer" to me, it should have appeared in my field of view to be larger than the height of the bars that were further away. Yet it wasn't, so the net result was that the object appeared to be somehow bound by an invisible bar or to be behind a bar which it was clearly in front of.
Obviously, this effect is only kicked down the road a foot or two when you open up the matte to an academy aspect- during gameplay, Master Chief's rifle appears to pop out of the screen somewhat, but is somehow bound by the edge of the projection/screen, which is theoretically further away from me (at screen depth). So the same problem exists, just lower on the screen.
But since a lot of objects are "round-ish" or "taller than they are wide" (i.e. people), these objects are more likely to be bound by the top and bottom of the screen than the sides. So a more "roundish" aspect that allows these items to be less bound by the edges of the picture.
Disney's G-Force had an intersesting solution to this I'd like to see more in use- that is that super foreground objects were allowed to break the matte that surrounded the picture.
