I agree joining the E-mount is their best bet.
The diversity of 3rd party selection is insane.
It's the most developed Mount at this time. The majority of research resources from Samyang /Cosina /Tamron is spent on exactly the E-mount. And the newer Chinese startups are following the trend.
If you take Leica as example, they pretty much doomed their new Full Frame camera by not making it E-mount. These 9 lineups were never ported to the Leica SL, so Pentax would be wise to avoid that fate.
