I have been calling the upcoming release “D&D 5.5”, but now I think it would be better to refer to it as “D&D 5.2”. Here’s why. After the release of the Player’s Handbook (Sept 2024), Dungeon Master’s Guide (Nov 2024), and Monster Manual (Feb 2025) Wizards of the Coast will release an updated versi
...the SRD 5.1 corrected several oversights from the first-draft SRD 5.0 released four months earlier, but didn't in any way reflect changes to the actual published game, which remained substantially unchanged until tasha's cauldron of everything was published five years later, effectively revising several key classes, races, and other core design mechanics, setting the stage for other forthcoming proto-sixth edition revisions including spell-like abilities and deprecated alignment...
...calling the new SRD 5.2 is purely a marketing decision, as it will be an entirely new document rather than a revision to SRD 5.0/5.1...if any point in fifth edition's ten-year history merits version update, it's the revised game design WotC have been publishing since 2021...
Are you quoting something with those ellipses?
If "5.2" were a marketing decision, then it would probably be getting used in their marketing materials. But there you see stuff like "One D&D."
Incrementing the second number here is in line with general "geek numbering system" convention. It doesn't seem to me like marketing barged into the production room and insisted on a more "marketable" version number — not that that has never happened, but marketing would most likely have wanted "5.5" not the inscrutable "5.2."
