Well fans do the same with Godzilla movies since the films from 1999-2004 as label down as Millennium era films when they are still Heisei. Even Godzilla 1984 is list as a Heisei film despite coming out in the Showa era.

W-Ghost are still Heisei, but I don't care if fans use the term "Neo Heisei" for them. I just call W-Ghost as Post-Decade Heisei shows.

The Millennium Series is an official term used for that group of Godzilla films though. Not to mention that there's a clear split between the Heisei and Millennium films there. "Neo Heisei" has just come about because people seem to think that because Decade is an anniversary series that encompassed the first 10 years that what follows suddenly needs a whole new designation.

Well then I guess that I should call everything after Gaim 'Post Gaim Era".

Again Neo-Hesei is just a stupid fan made term that really shouldn't exist. The official people at bandai don't call it that so why should fans? If it Transformers it makes sense, Godzilla was split into three different periods because there was a very clear divide. Although honestly though we could make anything a "Post era" because this "divide" started at Den-O to an extent.

Again, I'm not sure about a source on this, but I'm pretty damn sure Toei HAS referred to W on as "Heisei Phase 2," so they do officially acknowledge some kind of divide between Decade and W.

Can you link to an article that states this, because if your only defense is "Oh I [I]think[I] I remember them saying something then thats a pretty damn low level defense. Any one can claim that they remember something but without proof, its all bull.

While I don't know whether or not there is any official term, there were a series of changes made to the franchise with the intent on steering it in a different direction in terms of marketing and content.

Hey, I never said it was a strong defense. In fact my intention by prefacing the statement with "I'm not sure about a source" was supposed to make that known. I'm obviously unclear, but it's something I've heard. And If I read it on the internet, it MUST be true, right? :p

Whether the divide has an official name or not, I think the biggest evidence that Toei/Bandai DID intend a separation from W onward was the fact that before then, the series was titled "Masked Rider" but after-the-fact it was re-branded as "Kamen Rider," probably to attract international fans of Dragon Knight. I see that as the signal of (if nothing else) a new generation of Riders. I think it's just easier for some fans to acknowledge that clear marketing shift with its own category. And if we're going to refer to that new generation seperately, might as well give it a name for convenience sake.

How does that even work? Kamen means Masked and it was always Kamen.

Whenever the title or series logo would have the romanized version below it, it would say "Masked Rider" and since W it's said "Kamen Rider" instead. Just look at all of the S.H. Figuarts. Any Rider design predating W says "Masked" on the box, and any one afterward says "Kamen."

After the Megahex incident, what if Takatora & Akira dated and got married? I wish his gaiden movie would've shown Zangetsu using a jinba form with "Jinba Melon".
