I feel like they've been clear, consistent, and honest about what the new books were going to be from the start.
Yes. Which is why we've been pushing for them to call them the correct name.
I ALSO feel (unlike you) that the term "Edition" has never once been consistently used throughout TTRPG history, doesn't work very well, and is best left to rest.
Can you give an example? How is edition used wrong? Remember, there can be several correct ways, so one company going up a 0.5 and another going "revised" - both showing incremental changes as opposed to a whole new editon - is not "doing it wrong". I can give plenty of examples where it's used right, from AD&D to 7th Sea to Call of Cthulhu to what have you.
So... am I being dishonest too? Or does WotC and I just disagree with your assertions? Maybe, consider, that we just don't agree.
Boeing can disagree that a door blowing off their plane is a bad thing, that doesn't change that it was. We have a meaning for edition, even if it's not formalized, through decades of use. A company or individual disagreeing doesn't change that.
They're actively calling it "Fifth Edition Revised" and that's really as good a name as any.
And that's a just fine name. And a change from "Fifth Edition". If they had been calling it for the past two years we wouldn't be having this discussion at all.
You might prefer "5.5" or some other (IMO silly/wrong) name, but that doesn't make your choice better and my choice dishonest (rude) - it just makes them different.
I'm fine with "Fifth Edition Revised". Because it shows that it's not "Fifth Edition". A point we've been trying to get them to admit for two years. I'm glad to see that they are finally acknowledging that it's not Fifth Ed. It would have been a lot more honest if they didn't repeatly claim the opposite, and then proceeded to sell two years of books, many with character options that are aligned with the 2014 PHB.
We can even leave this part be - I acknowledge that they are now calling it "Fifth Edition Revised", because it's a fact, and you acknowlegde that they pushed that it was "all the same edition" until this year, which is also a fact.
Please though, you called 5.5 "wrong". Using the example from WotC of what a half increment edition change is, from 3ed to 3.5, please give specifics about why it's wrong. Get it to the "Net Wrong" side of the page, that there's more wrong with 5.5 than right.
