I'm sadly expecting most if not all of the current animatronics to be scrapped due to their basic shapes not fitting with PATF's characters. Most of SOTS/Splash's animals are extremely "anthropomorphic", which is a hybrid of animal AND human characteristics and proportions. The type of designs also used in Robin Hood, Great Mouse Detective and Zootopia. PATF uses more realistically shaped animals such as 101 Dalmations, Bambi and Lion King.
There are a few smaller simpler figures that could possibly be reskinned such as Roadrunner, Mr Bluebird and the squatting toads or turtles. They're proportioned more like real animals. But the larger frogs, rabbits, foxes, chickens, geese and most other characters use anthropomorphic designs and don't remotely fit with the animals in PATF. But nor are their shapes suitable for reskinning as humans either.
Louis might be an exception. He's the only real animal who learned to move and walk like a human. His size and proportions might possibly work as a reskinned Brer Bear figure. The frog versions of Tiana and Naveen also move around like humans, but allegedly they're only appearing as humans in the ride. Even as frogs, none of the ride's figures fit their designs.
I expect the new ride will be very sparse and video-heavy with very few animatronic figures.
