With the first day in China of 107 million and Boxoffice Mojo's initial weekend estimate of 300 million in North America, I have to say yes. I would put the chances at greater than 50% that Endgame will set that amazing record. With 4 days left in China, I think 327 million is a reasonable estimate for China and if Endgame breaks 300 million in North America, the total for those 2 regions would be 627 million and would only need 373 million from the rest if the world.
