There are credible rumors that Disney no longer finds Marvel comics profitable, and that by 2030 they may stop publishing physical copies of comics and will make all new material digital instead.

Guess no one wants to comment on this, but I doubt it will be the end of Marvel comics altogether. Disney probably wants to sell off the publishing piece of it to a third party figuring to still make the films. If anyone will be interested, well it depends on what's in the deal.

Publishing the comics themselves may not be necessary as long as they retain the rights to the characters. They can just do original stories not based on any previous source material. The way Disney has been butchering up the latest instalments, the writing could hardly be worse.

Comics and graphic novels may not be profitable by the standards they want, but people still like them. It's the publishing costs and lack of advertisers that is causing print to disappear. Digital copies are not the answer as many people who read comics will not convert and just drop it. It's just the nature of the thing.
