Let’s also remember that Chapek more or less put Eternals’ theatrical release date on the shoulders of SC, the first MCU origin movie featuring a title character in their first appearance in that universe since Doctor Strange 5 years ago. A lot put on the shoulders of a 1970s-originated D list superhero, Nevermind in the wake of BW’s performance and the thinkpiece gold that produced.
so yeah, no day and date crap for Eternals.
