The concept art also matches up very well with a Pandora's Box ride system. So?
The concept art shows essentially nothing about what the main E-ticket ride will be like, beyond that it will simulate riding on a banshee on Pandora. In terms of ride system, we only know what the insiders have indicated and the concensus recently has been that (1) the leaked blueprints are no longer the current plans and (2) the ride is supposed to move from place to place, not just be in front of one screen. That doesn't meant that things cannot change, but it seems to be where we are now.
Someone (I think Martin, but I could be wrong) also mentioned that to appease Cameron for taking out the third ride (that they want to use for Star Wars instead), that Disney has committed to really plussing the remaining planned attractions and land. If true, then hopefully that would mean a true ground breaking experience for the E-ticket.
