Again, please read my actual statement ...
"there is a reason no electronics manufacturer designs products to use RCR-V3"
Again, please point me to
devices that have microelectronics, such as CMOS microcontrollers, CCDs, etc... that
use RCR-V3s?
No one has yet. I'm still waiting. In fact, not only do they not make 3V devices, but even 3.6-3.7V devices (Li-Ion's normal voltage under load) do not. That was my point.

The only thing I do agree is that the trend is towards more proprietary batteries like K10D & K20D.
Every, single, complex device with CMOS microelectronics, CCDs, etc.... on the market that takes Li-Ion
always uses their own, proprietary 3.6-3.7V, 7.2-7.4V, 14.4-14.8V, etc... batteries.
I'm still waiting for anyone to point me to a device that
uses a standard RCR-V3 -- let alone multiple!
The variance is absolutely too great.
There is not a Li-Ion battery available with cells that output 3V, period.

Considering the K100D/K200D are 6.5V "max," that's already working the regulator beyond what it's designed for.

All Li-Ion batteries are "regulated." How they are regulated, and how they use the Li-Ion cells is of interest.
Many of these "nearing 3V" designs drastically reduce the current-time, as well as reduce the "safety" on the cell (that prevents them from reaching the "dead" voltage threshhold) and other issues.
I'm not making this stuff up. If you use RCR-V3, you deserve the issues you get. There have been many, many people who talk about the AF being fast, but "the most they have to do is turn off the camera and turn it back on again." The root cause is transconductance in the microelectronics due to over-voltage. Even if you don't fry it, you reduce the longevity of the microelectronics -- let alone the regulator.
