Let the 'Toy Story 4' rumors begin! (Again!)

Pixar announced today release dates for four upcoming projects from 2016-2018, three of which were previously unannounced. So, let's get into some big-time speculation to see what lies ahead for the future of Pixar Animation.

The first one is easy. A June 17, 2016 date was set, very likely for the 'Dia de Los Muertos' film directed by Lee Unkrich ('Toy Story 3'). Pixar had previously announced a 2016 release and this June date is when we'll see this movie. The as-yet-untitled film is described by the studio as "a wholly original Pixar Animation Studios film that delves into the vibrant holiday of Día de los Muertos."

The remaining three Pixar release dates are for June 16, 2017, November 22, 2017 and June 15, 2018. So, what are these films?

Back in 2012, 'Safety Not Guaranteed' writer Derek Connelly revealed he went to Pixar to write a film for director Teddy Newton (who created the Pixar short 'Day & Night'). And director Mark Andrews said, after he won the Best Animated Film Oscar for 'Brave,' he's returning to Pixar for his next film. ("I'm currently developing another feature film at Pixar Animation. Gotta stay busy!" said Andrews at the time.)

Those are two projects we know about (even if what we know about them is very little). Which leaves one date left for another highly-rumored Pixar project... 'Toy Story 4' anyone?

Pixar has remained very quiet on the subject, even though many people have been buzzing (pun intended) about another 'Toy Story' film for the past two years. Even Tom Hanks said when asked about the possibility of a 'Toy Story 4,' "I think they are trying to do another one."

Now, as we've seen in the past, Pixar is not shy about canceling a project if it's not working out (see: 'Newt') so we can't guarantee any of these films match up with any of these announced release dates. We do know that the average Pixar film takes about 4-5 years to produce, which means that they're just cooking up some things now for that last 2018 date.

What would you like to see Pixar do? Will you be happy if 'Toy Story 4' is one of these films? Will you be disappointed if 'Cars 3' is one of them?
