That is called doing the bare minimum - I'm all for Avatar if they are going to be using brand new technology in rides or even the I-ride system or a whole new system - to at least equal one of the following: Spiderman, Transformers, FJ or hell Gringotts.
Well, to be fair, we can't know if it's the bare minimum or not until
we experience it. It could be that some small modifications to the motion system,
the screen (dome?), adding 3D, shooting at high frame rates at IMAX or better
resolution . . . could really make for a remarkable new sensory experience.
All of those things are likely given Cameron's penchant for new immersive filmmaking
technology.
Think about higher resolution than IMAX, with high frame rates, in 3D--it could be like looking
out a window into a new world, like nothing we've seen before.
I highly doubt, but hey we're all just guessing here, that it will be simply Soarin 2.0.
