With Saldana's schedule open and Ice Age 6 out of the way, Rio 3 may finally begin production very soon.
Rio 3 wasn't announced at D23 because with Saldana finishing 100 Dais and Ice Age 6 out soon, it is most likely still in pre-production. I'm disappointed just like everyone else Rio 3 didn't get an update at the D23. However, it's not because of a lack of interest at Disney but a very unique development hell. There is also the fact D23 focuses on movies in late production or post production as their release dates are in the next 18 months. With various obstacles Rio 3 is more in pre-production than production.
Blue Sky Studios closed down back in 2021, but since Buck Wild was in the middle of production and Rio 3 and the spinoff were in development Disney was able to save animation assets for Ice Age but had to completely rebuild Rio's from scratch. They're primarily using Ice Age 6 for name recognition but also a Guinea pig to test the new pipeline and animation before they can use it for Rio 3. Carlos Saldana, the director and creator, didn't give us Rio 3 in the 2017-2019 window has he already had a busy schedule. He's made it clear he wants more Rio films but for the last 4 years he's been busy with Harold and the Purple Crayon and 100 Dais. With the former released and the later coming in October his schedule is now open.
The movie has been in active development for 4 years so they no doubt have a script, animation team, storyboards, concept art, etc all ready. They also know they want to bring back the original cast who are openly eager to return. Now that they have a director and the animation equipment at Fox is open it can be safe to say we may see production begin immediately once Ice Age 6 is in theaters. The box office may even help fast track it. This would also give us a release date for late 2028 or early 2029 with updates at the 2027 D23.
The Nico and Pedro spinoff hasn't had much updates, but has had some of the same problems. However, they found a different director and got Bardel to animate it. Streaming films also have different pipelines than theatrical films and usually don't get as promoted as much. It is highly likely Disney plans on releasing it at least a year before Rio 3, which from a corporate standpoint would be the best way to promote Rio 3 and increase the nostalgia hype.
Despite the disappointment with no Rio 3 news, with Rio's biggest obstacles out of the way we may finally see this franchise fly again very soon.
