Disney/Pixar have confirmed the date changes, with THR reporting that an accelerated schedule for The Incredibles 2 was what led to the change. Since The Incredibles 2 is undoubtedly one of the most-demanded Pixar sequels, this development will come as a pleasant surprise for fans. Now, the Parr family will return to the big screen a year earlier than anticipated. As it stands now, The Incredibles 2 will open on June 15, 2018, and Toy Story 4 will reach theaters June 21, 2019.
As for how this impacts The Incredibles 2, viewers should be able to learn more details about the film sooner, as 2017 will be a busy year for Bird and his team. Everything from the cast to a general synopsis remains under lock and key for now, but that will most likely change in the near future. It will be interesting to see what Bird ultimately comes up with; he recently teased the “new directions” the characters will go in and has repeatedly discussed the challenges he faced while crafting the story. It’s clear that he has a fondness for the material and obviously wants to do it justice. Fans have been clamoring for an Incredibles 2 since 2004, so it would be a shame if it disappointed.
Now I NEED this sequel to slay my life, I'm not about to accept **** after so long. They should've capitalised on the first one sooner tbh, it could've been huge franchise. Oh well! better late than never yaaaas
