A previously rendered cartoon presentation that is not at all improvised and never changes. It could be that.
I imagine we'll at very least see a full-scale build of the simulation training system seen in the last Cars film.
And if you take the PR speak literally, they do say Lightning will be on stage LIVE, but then they also go on to talk about the 200-foot long screen, so who knows. I bet he's show us some of his moves in the simulator though. (Wonder if that means we'll be seeing his but the whole time?)
Excerpt from
here, emphasis mine:
Taking on the role of rookie racer, you’ll cruise into the theater and find yourself face-to-face with Lightning McQueen, appearing live on stage. McQueen and the entire audience are enveloped by a giant, wraparound screen that is nearly two stories tall and stretches more than 200 feet from end to end, pulling everyone into the action! The racing legend is excited to showcase what he’s learned over the years. Of course, as Lightning McQueen has discovered throughout his career, things don’t always go according to plan, and he has to think fast to get back on course.
