Such a nice quote. Exactly what I want to hear. Too bad it's not only kind of true.
I don't care about the terminology. Whether or not it's a "new edition", OneD&D is a more substantial redesign than I wanted, and, I would argue, more of a change than a 5e player whose only knowledge of OneD&D is this quote would expect.
I would have loved getting a modest update to the 2014 PHB to bring it in line with late 5e design principles (even if I think some of those principles are silly... I'm looking at you Mr. Ubiquitous Repurposing of the Proficiency Bonus For Everything). I wanted PHB Ranger and Sorcerer subclasses to get some free spells, Magic Initiate to be rewritten to work like later, similar feats, and a few other tweaks, and would have also been happy with a more substantial reworking of races given what a mess that had become post-Tashas. The 2014 Monster Manual always needed another pass and was just too much material to create all at once for a game that hadn't had much roadtesting, so even if I wasn't crazy about some of the Monsters of the Multiverse era tweaks I think 5e monster design definitely got better and the MM needed an update. The DMG... well I don't really care, it's not something I get much use out of, but it could probably be organized better, maybe then I'd get a little more use out of it.
Anyway that's what I wanted, that's what I think I would have expected if my only OneD&D knowledge was this Jeremy Crawford quote. After the 1st playtest I thought that might still be what we were got. But then we entered this weird world of the later playtests which I see as generally being an approach of pushing the boundaries of what can be called 5e compatible. While I am on the "yes OneD&D is still compatible" side of that debate, that doesn't mean it's not still more of a change than I would like or than I would say this Crawford quote implies.
Of course the product I really wanted would be a big book of all the 5e player option materials, so I wouldn't have to truck around and crossreference a small library just to run a PC, and that would be a great place to do the level of light updating I wanted to PHB content. But that was never going to happen. WotC would much rather people buy many books than one, whether or not it's convenient to actually use.
