The LPS system has technically "evolved" quite a bit since Pooh TDL, and I've heard it is the system or format for Rat in DLP.
TDL Pooh's ride system still looks pretty advanced when compared to stuff in the states, but I guess one way to evolve this system would be to allow for a much greater range of pre-programmed special movments, (such as how the Honey Pots "bounce" with Tigger being a special movement). Instead of just a bouncing motion, the LPS vehicles could possible have a greater degree of motion which involve tilting, and other motions.
Given the scenes in Ratatouille that will be put in Ratatouille Kitchen Calamity, i.e. a rat running crazy all over the floor of kitchen while it dodges feet, falling food and possibly brooms, the steady motion of Pooh's LPS system just doesn't cut the cake, IMHO. We need an LPS ride vehicle which twists, makes relatively sharp turns, tilts, speeds up and slows down quickly.
I guessing these are the "evolutions" in the new LPS system. I guessing that we'll be seeing cup shaped LPS vehicles for Ratatouille. I think the attraction might have:
1. Queue. An underground "sewer" with animatronic Emille talking to guests as he eats some "food" he found in the sewer, in addition to Remy talking about how he wants to show people how he became a chef.
2. Guests enter tea cups LPS vehicles, I guess the rationale would be that they are floating in the water in the sewer, and you exit the sewer to see Remy at the house where he first learned to cook, we see Remy watching television while he tries to cook. The woman who owns the house can be seen in the background as we exit . . . ominously reaching for a broom.
3. Remy in Paris gazing at Gasteau's, LPS vehicle maneuvers around a small recreation from a rat's eye view with a river on one side and Gasteau's on the other. Random motions as the vehicle swirls around while Remy talks about the beauty of Paris.
4. We are in Alfredo's apartment scampering along a shelf, and we see the first oversized human, it is Alfredo's gigantic head telling Remy to get under the chef's hat and stay out of trouble! A big scene where Alfredo's gigantic head pops up and surprises the guests.
5. Remy narrates about how things didn't go as planned and we have the big free for all scene on the floor of the kitchen, things are flying everywhere as the tea cups tries to stay underneath a table. People are yelling rat! Tea cups aren't illuminated, so you get the feeling that there are a lot of "things" under the table with you, sort of how rats scurry around in the dark.
6. Next scene we are underneath a food tray which is opened just a bit and we see a sliver of Anton Ego's gigantic head, enjoying a meal we cooked. "Who cooked this, this is excellent!"
7. Final scene, Remy with friends and family in a rat restaurant on the top of Gasteau's with a big Gasteau's sign in the background. We see the eyes and top of Alfreddo's and Colette's heads as they spout random lines, like, "boy your little rat friend knows how to cook!"
8. Exit back to the sewer. Finale scene is Gasteau's cook book propped up against a wall with a page opened which shows Gasteau. Emile is sitting next to the book, rubbing his stomach and complaining about something he ate giving him wild dreams.
