But they did, and in doing so they opened my eyes. The game post-Essentials will be fundamentally different to the game before it. I personally think most of the changes are good ones and I'm looking forward to seeing how they turn out (and I LIKE that WotC is still working on improving the game), but I think it's disingenuous and/or naive to consider Essentials anything other than a new iteration of the game.
Was the game fundamentally different when PHBIII came out or when any of the splat books did?
Essentials is just a bunch of new classes - they break out of the existing power structure, but they are additive and (hopefully) balanced content - and some errata and new rules. It is fundamentally not going to change my game any more significantly than adding the PHBIII to the mix.
I think this is the litmus test for new editions. The line gets fuzzy with some of the early editions of ADND, but they were intended to replace all the classes even if they were pretty compatible.
Anyway it doesn't really matter what people called it, although using the x.5 nomenclature carries a lot of pre-4e emotional baggage - mostly negative, it is the awesome sauce...
