I guess importantly that this new shutter assembly has terrible mirror slap given the violence and speed the mirror is being pulled by the solenoids first this way then that? It will be interesting if it is ever implemented in a working camera and how it fares. Interesting engineering concept though.
I have a 10 fps camera and I can tell you weeding out images post a session is a nightmare. I find I use the top fps speed less and less preferring a slower speed and more control.
Superfast shutter speeds appear to be useful and it is great to have that facility but it is useful only in some circumstances.
