The other thing people seem to be overlooking is that Chaser is coming out 4 months after his show has finished. The window for it being a mass release item has long passed.

That's true, but it more shifts the complaint to "why wasn't it released earlier?" than anything.

I mean, I personally find it a little weird that the retail releases for Drive were all released over a period of less than 4 months. Seems like an oddly small window to get out the really important stuff...especially since in this case the retail releases only covered stuff up to around episode 16 ish of the show. I know that Gaim released stuff until late last year, since I think Kiwami Arms came out around November? But maybe that's just Gaim being Gaim, I dunno how it usually works...

It does raise the question of what they'll do with Type Tridoron, though, since whenever he does come out, it's going to be even later than Chaser. Having the final form of a main Rider as an exclusive would be really weird. But it could happen, I guess.

Well to be fair Chaser did debut kinda late in the show. IIRC, the only riders/forms to debut in the show after him were Type Tridoron and Gold Drive, not including movie riders/forms.

Drive also appears to have less merchandise to sell overall than Gaim, so I imagine they're trying to space out their releases so that it can still be a profitable series alongside Ghost.
