I think the direction Playboy is going is fine, I certainly don't expect every model to pose as explicitly as some recent videos. Quite frankly Playboy is using quite a variety of models now, drawing from different sources. They use many different European models who already have a history of doing more explicit "pink" work including finger penetrations and lesbian vids.
Recent model Kylie Morgan apparently is a popular camgirl... her pulling open her asshole really took it to another level though...
They have used hardcore model Natalia Starr a few times and she probably had the most exposed open pussy view I've ever seen Playboy dare to show...
Michaela Isiuzzu is a popular Euro model... but really you can find her fingering herself at sites like X-Art, so the PB stuff is tame by comparison...
It is nice when there are models exclusive to Playboy who surprise you by being naughty when you don't expect it and seem to enjoy spreading their legs to give you a peek. I kind of avoided PB vids for a long time but the sneaky peaks Cybergirl Jennifer Vaughn would give got me hooked a while back...
I think their should be variety to the videos and different levels of explicit posing... I really think in the future
You Might see the envelope pushed ever so slightly maybe with some rubbing and one day a quick finger insertion. That's how you maintain interest in your product, you make such the viewers want to see what comes next.
