I believe it has been confirmed that Indy does not die in this movie.
But I also think there were some early rumors (which have since been debunked) about Indiana Jones passing away at the end and Phoebe Waller Bridge taking over... but I recall watching the TV series from the 90s where he was older than current Harrison Ford and also sporting an eye-patch... does Disney/Lucasfilm consider the series canon?
Maybe he'll lose his eye in this movie.
shareI believe Lucasfilm CEO Kathleen Kennedy fully intends to hand over the reigns of the “Indiana Jones” character to a female at the conclusion of this episode.
shareFor Indy to have aged visibly AT ALL, it would have to mean HUNDREDS OF YEARS have passed.
How old was the knight in the third movie that drank from the cup? Indy drank from the Holy Grail, so he essentially has drank from the fountain of youth - 'every man's dream' - so ANY visible aging, as well as any masonic eyepatch-symbolism makes NO SENSE at all.
After all, it's not only about slowing down aging, it also HEALS WOUNDS instantly, so he basically shouldn't be able to lose an eye or injure it enough to need a masonic eyepatch.
