You mention 10 years from now. I won't predict what's going to happen in 2027. But I can tell you what happened in 2004 and what's happening now and comment on that.
Back in 2004, my pull list was 75% Marvel to 25% DC, Dark Horse and Image. I was buying Marvel over DC at a ratio of 2-to-1, maybe even 3-to-1. That is no longer the case. And in 2007 after OMD, I dropped all Spider-Man books and never bought them again.
In the past year or two, Marvel has started regularly overshipping "free" copies of books to retailers. I say "free" because retailers do have to pay for the shipping costs on those books, most of which end up as unsold product shops are stuck with and ultimately stick in dollar book bins or 50 cent bins or simply give them away. These overships started at 10% and have increased to 15% on some titles. My question is, how high does Marvel keep increasing those overships--20%, 25%, 30%--before the numbers make it untenable to continue giving away their product for free?
I have no beef with Dan Slott at all. By all accounts, I hear he's a nice guy and a successful writer whom I respect. But I fail to see how spending your days criticizing fans who stopped buying Marvel's product because they didn't like it and how they are all dumb, wrong or foolish for wanting Marvel to make product they want to buy is a winning strategy.
Marvel Comics is a business. They want and need to make money and they want to beat all of their competitors and hold the #1 position in sales. Like it or not, the customer is always right. The comics retail business rests solidly on a sales base of older, white, straight male customers who are proven resistant to change and can hold out anyone for years, if not decades. Me personally, I don't care which version of GL DC publishes--Hal, John, Kyle, Guy--as long as the stories and art are good, I will buy it. But I'm in the minority and sales figures prove that the fans will get what they want if they vote with their wallets. That isn't an opinion; that's a fact.
Marvel could go the route of undoing OMD and restoring Peter and Mary Jane to an earlier point where they weren't married. DC has proven fans will accept and buy this reset trope with Aquaman, Flash and Wally West in Titans. It can be done and sell well. But the harsh reality is that most customers do not join or even read online forums. The vast majority simply add or drop books from their pull lists without ever interacting with creators or other fans online.
The bottom line is, if the sales figures for any and all Marvel books continue their steady erosion where Marvel keeps increasing the number of free overships, then eventually the profits simply won't support continually giving away free product in ever increasing numbers. That isn't my feeling or opinion; it's basic math. It is Economics 101. No business can maintain profitability on a sales strategy founded on giving away their product for free.
Also, arguing with and criticizing your customers is a lousy way to get them to buy your product. If someone walks into a store and says they want a certain product and the salesman tells them, "Too bad. This is what we're making. Now shut up and buy it," that customer can and will walk out of the store and go to your competitors and buy their product instead.
I never, ever thought Trump could win. It was impossible. Saying that Marvel will always be #1 and no one will ever bring back a story element that the people running the company have insisted is gone forever is unrealistic. Sales can certainly drop lower. And they can continue to drop to the point where the people running the company will in fact be forced to do just about anything to claw their way back to again win over customers they alienated.
Never say never. The impossible can and does happen. Not because I or other fans want it to. But solely because falling sales figures and pressure to increase sales and regain profits will force comics executives and creators to say and do things they swore they never would.
In the eternal battle between the need to be creative and the need to make money, money always wins.
