@Rico, you answer @Kunzite that:
No it is not. UHS-I and UHS-II are technical STANDARDS. It is the implementing HARDWARE that matters. The K1 does not fully implement UHS-I speeds due to HARDWARE not being fast enough: if it did, the write speeds - using your stated 35MB/s - would be three times faster. That is not an issue of the bus standard, that is a limitation of the HARDWARE.
I do not disagree that a future, better performing, DSLR would need the faster write speeds that are available by implementing UHS-II. I totally disagree that it is the only thing that needs to be changed to achieve those faster write speeds.
As @Kunzite suggests, the next iteration of hardware will probably follow the GRIII and use a totally different processor architecture running Linux based OS. That will enable the use of much faster multi-core processors and hopefully solve the slow hardware issue.
Everything is cured with faster hardware (provided it has efficient software...)
:)

Exactly what I said!!!
It's not the UHS-I bus speed that is the problem.
It is some part(s) between the sensor and the SD card that can't keep up with the maximum possible UHS-I speed. We don't know what the bottleneck is, but it is not the UHS-I bus.
Ergo: putting UHS-II in a K1 will make ZERO difference to the write performance.
In comparison, the Olympus OMD-M1ii has two quad-core processors in the data pipeline: it can justify use of UHS-II bus and suitable UHS-II cards.
The next Pentax DSLR may have UHS-II, but there is no point if the rest of the imaging system can't deliver the data fast enough.

The K1 does not get close to the maximum write speed of the UHS-I bus (104MB/s), the hold up is somewhere else...
...without the whole data pipeline being upgraded, UHS-II is an expensive (as in the media cost) waste of time.
@Rico, are you on commission from the SD association??? Please just give it a rest.
When the next Pentax DSLR comes along, I'm sure it will have suitable components that match the performance of the whole, not just the SD card...
:cool:
