All the signs for Toy Story 4 are looking good. (Of course I have to caveat that with presales haven't been a sure fire indicator but still positive leaning.)
The Pixar movies have been trending up by quite a bit lately. With the previous Toy Story starting off with a 110m opening weekend, and last year's Incredibles 2 bringing in 182m opening weekend, expecting a bump for Toy Story 4 is very reasonable. While a few places are predicting 200m, I'm a bit more conservative as I don't expect it to out do Incredibles 2 in OW or whole run. However Toy Story is a more beloved series, so if it does hit that mark I would not be surprised.
