I am saying that if you frame a shot in LV mode, you now have the mirror up. Right?
So, why can't you press the shutter and get continuous shooting (fixed focus) without the mirror coming down and up again?
This way would you get a higher frame rate?
For a high frame rate you also have to be able to move all that data, by the way, so there are more bottlenecks than just the mirror and shutter.
Why some cameras need to move the mirror to cock the shutter? Because that is how their mechanisms are built, is the only answer I can give. Other DSLRs have separate motor mechanisms for each, and can cock the shutter without using the mirror motor.
And why use the mechanical shutter? Because the sensor lacks a global shutter, for instance, and you get a "rolling shutter" or jello effect with moving subjects, for instance.
So, a combination of these factors is where your answer lies.
