Not related to movie making or history
Um... it is literally called the "Universal Timeline". Those posters are of Universal films throughout the years. Depending on the Tram Guide, they use a few of those posters as a reference to talk about the film making process or as an intro to pointing out soundstages (specifically SS12)..
As someone who LOVES the old Breaking Bridge attraction, I at least know that they can't just "bring it back". Besides, it needs to be restored.. The tram already has to loop around because of KONG 360, if the Bridge was included, that'd mean it'd have to loop around TWICE.
As for the old Fast & Furious attraction stop, you can't change it to something like Bourne. It'd just be the same experience except with Mini Coopers. However, since it is right before the Jurassic segment, the small industrial themed attraction space could be easily converted into a Dino Encounter (Indoraptor? Carnotaur?).
As for the "Lower Lot Redesign", relocating the Studio Tour to the Lower Lot would be interesting, since Jurassic World sits where the old tram load/unload used to be years ago. The issue is of course the space required for the Studio Tour queue, load, & unload. Plus they'd probably have to relocate the tram maintenance garage as well.
I don't see a Studio Tour relocation happening yet, especially since they just revamped the entrance just a few years ago.
