It's slowed down a lot. The only noteworthy japanese pinku/softcore erotic movies nowadays (in the past decade or 2) are generally the ones with crazy costume play that visually stand out (Iron Girl, Lust of the Dead, Lady Ninja, Missing XX etc). But unlike the flower & snake series and other classic pinku movies none of the new ones provide good "chakuero" shots.
They're mostly only good for introducing you to new JAV stars as the production values and scenarios of the wacky pinku/softcore often make the girls look a lot hotter than they would in a random jav, and then seeing them actually act out a character first serves as a tease, puts them up on a pedestal compared to a chick who's already explicitly sucking and fucking in a JAV first time you see her.
