I wonder if they could update the preshow when/if they update the ride. Maybe give it a new host and update the ride narration audio as well. If Disney wanted to be cheeky they could get Chris Pratt.
Of course, other than damaging the theming in Dinoland as a whole, there's no real reason the preshow couldn't be animated. If they really wanted to have fun they could license Rick and Morty.
First off, I didn't expect this thread to resurface...
Anyway, I don't think Rick and Morty is exactly Disney family friendly material, but that would be hilarious! I do agree that a new host is due though, I'm just not sure who or what it would be. Some new scenery as mentioned before would also bump up the immersion of the ride and make it less of a warehouse with some leaves ridethrough. Maybe a couple small new animatronics could be added too? Let's just hope that the ride gets a big refurb after Pandora opens.
