Homecoming is at 706 mil and counting. With another 20 days before its China release, we're looking at about a 715-720 worldwide gross by the time china releases. 100 mil is guaranteed in china with ASM 2 doing around 94 mil. The only difference is since 2014 China has become a HUGE box office entity with much more theaters and much more catering from Hollywood in terms of Chinese appreciation. The MCU has become HUGE in China as well, especially Iron Man and combining that with Spider-Man's enormous popularity there you have a film that could become a smash hit in China. The film being very tech based especially seems like something that will be huge in China. I'm predicting it plays like a huge blockbuster and grosses around 150+ mil in China. For reference Ant-Man which had a late release in china similar to Spider-Man: Homecoming earned 105 mil in China to show the power of the MCU. Logan earned 120 in China, showing the power of a critically acclaimed superhero film. Combining the power of both and sprinkling a little RDJ in there should make for what I believe will be a very interesting and surprising gross for Homecoming's final box office stretch. I believe Homecoming will barely nudge out the 890 mil of Spider-Man 3 with around 892-893 Worldwide.
Imagine it as a part of the MCU. 
Won't Be Mad If It Does Tho, I Definitely Don't See It Beating 3 Tho..... This Movie Really Wasn't THAT Good To Get 890+ In 2017
