Since JJP#5 is likely going to be Toy Story since it was leaked when Dialed In! and POTC were originally leaked by the same person, I figured the JJP#5 speculation thread is more of a Toy Story anticipation thread. That movie is supposed to drop around June 21, 2019.
So what's JJP#6 going to be? If #4 is shipping Q1, 2018 that should put #5 around Q3 2018 but that would be ahead of the movie release. Maybe they'll sneak another Pat Lawlor original in around Q3 2018 as #5 and do Toy Story as #6 so it's timed closer to the movie?
