Yet that's what will inevitably happen, only faster than it does now.
And every update renders previous versions of what was updated obsolete.
Leading to conversations like this in about 2028:
DM: "OK, everyone's here. <lays out premise of game etc.>. So, I'd better ask which version of what books you each have?"
Player 1: "I have the Players' Handbook, brand new 2028 printing!"
Player 2: "I've got a PH as well, but it's from 2023."
Player 3: "I just look online for that stuff; (to Player 1) there's updates there newer than even your 2028 book."
Player 4: "I've got the '25 PH - yeah, it's the one they messed up on with those new classes, but it's all I've got."
DM: "So, four of you each have different versions of the same game; and mine is different again. Trying to unify them all into a single version is gonna be a pain in the d20 for me; and damned if I'll ask you all to go out and buy something you pretty much already have. Screw it - let's play something else."
This is my main complaint with today's business model: "sustained growth" is ultimately, in the end, unsustainable. Once a business is chugging along and making money, what's wrong with "sustained status quo" as a goal?
See my hypothetical conversation above. That's what it'll look like in the wild: instead of getting a different game every ten-ish years you're getting a different game every year or even sooner, despite vague nods toward backward compatibility.
