With the crown jewel of Phase 1 of DCA's remake (Cars Land) quickly rising to the fore in 2012, I believe it is not unrealistic to expect that new rides will later be added to the land that will be based on Cars 2.

The fantastic spy/international racing storyline and action scenes of the new flick would certainly lend themselves to a reved up second e-ticket to co-anchor with Radiator Springs Racers. Things seem to be flying all over the place -- cars, planes, bullets, missiles, torpedos, and (above all) intrigue and excitement! As I foresee it, a simulator ride (similar to Star Tours 2 and/or Universal's Harry Potter) is what we may be looking at! Or perhaps Disney might even gear up an awesome virtual journey utilizing Kuka Robocoater technogy. In either case, the storyline would likely reflect the film, starting out in Radiator Springs and taking our vehicular heroes to Paris, France. oui oui...
Now, I know that a D-Ticket and C-Ticket attraction have been rumored for the land (and not another E-Ticket). Sufice it to say mind you, this is Disney with a supercharged new attitude! So, who's to say that Disney is instead waiting to surprise us with E and D tickets.
