Well, if we can have 3.5 as 3rd edition revised, we can have a 5th edition revised.
At least this is WotC moving closer to a proper version number for this edition rather than call it "one D&D"
They never planned to call it One D&D and were clear (well, clear enough for me and many others, anyhow) that that name was for the
initiative of combining D&D the RPG with D&D Beyond & upcoming D&D VTTs and whatever video content they have planned.
"It's ALL one D&D!"
It was very similar to how 5e was never going to be called "D&DNext". Of course, they ALSO didn't want to call it 5e, but here we are... the community doesn't collectively cooperate with WotC's marketing, and never has.
We'll have to see what we call it in the end. Probably 5.5 (which I personally hate. Actually, what I really hate is when we're on a base-edition and people actually speak the words "five-point-oh" (which happened A LOT with "four-point-oh".) I had to keep saying, "It's just fourth edition!"
I've found that I really don't like how people like to call things by whatever
they feel like calling it, and not by what they're asked to call it. For me, the annoyance I think comes from TNG when Dr. Pulaski called Data "Dah-tuh".
In more recent times (and a more extreme example), it makes me think of
dead naming someone. Obviously the crime of calling the upcoming revised books "five-point-five" is not as
insensitive as dead naming an actual person, but still... it's in a similar range of stubbornly refusing to call someone (or something in this case) by their NAME.
It's rude and doesn't take a lot of effort to correct.
