Well some small players have been making regulated 3V RCRV3 though i.e. Juice, Lanmar, Delkin, Moby, POWERPLUS......Pentax does not make that.
And a big player Samsung does.
The only thing I do agree is that the trend is towards more proprietary batteries like K10D & K20D .
Some report (well in 05 ) with interesting test results
The Samsung regulated ones with 4 contacts
It measures 3.27V on the supply side to the camera
It measures over 4.15 V on the input side of the Samsung RCRV3
Even though it was in Chinese and in 2005 , it is just as relevant as today if only we can find in N Am the same Samsung crv3 batt + charger.

I believe the one that I have (Juice brand and Moby all have 4 contacts and giving out around 3.1V) are variants of what Samsung has. They are all regulated ones.
