For the last time.
No. Inside Out is not taking over Journey Into Imagination. Magic Eye and Wonders of Life is on the table. But Figment will maintain being the star of the ride. Disney is aware of his popularity and the backlash they would receive if they took him out, especially after the last 5 years or so of ramping up giving him a more prominent role and ESPECIALLY after giving him a new Meet and Greet.
stop fear mongering.
Figment is not going anywhere. He's recently made his first two non-park appearances (outside of the comic) in a children's book and Disney SpeedStorm. Slap on continued investment into the character thru festival merch and the meet and greet, and that is not a character on the way out. Figment has a level of protection seen in things like the Tiki Birds and Haunted Mansion.
The absolute worst case, mind-numbing scenario is a crossover ride, but that's NEVER been on the table.
Figment is safe. Inside Out placement is aimed at Magic Eye or Wonders of Life, with both focusing on the same end goal (an AA focused show akin to Cranium Command).
