The combination of built in SSS and the ability to ramp up ISO to achieve a higher shutter speed may eliminate this problem without the need for mirror lift. With regard to shutter speed at 10fps it is good to have the odd occasion when fast action has to be photographed. The shutter need not have half lift as a result as most pictures will be taken as single shot. For prof. sports photographers it might be just the camera if the AF can keep up with the action and more lenses become available. I am also concerned about my current lenses and 24Mp APS-C. For me 16Mp in my A580 will do. Need to wait for release and then tests and user reviews. In any event I will not buy any new camera until it is supported in LR as I always use RAW and Sony's software is sub standard.
I think you might have misunderstood my intent with the mirror lift capability alphaomega, I’m not for a moment suggesting that the mirror should be able to respond shot to shot, what I mean is that you should be able to press a button and the mirror slides gently up out of the way. Put it this way, your working off a tripod at whatever the current circumstances prescribe, be it Commercial, Architectural etc. and you have the focus set, you have exposure and composure set and then just before the shot you press the button for mirror lift; you then take the shot (after confirmation that the mirror is in the locked up position), which cancels the mirror lift and it then returns gracefully to it’s normal position, no need for any rapid or violent movement, it’s just a facility that should be there in a 7 SLT as far as I’m concerned.

ps. So far Barry and artington, the A77 isn't looking like something high on my desire list, mores the pity, it could have been such a great camera (at 18MP max) if the focus had been to make a top class still camera first and foremost and have video (if you must) as a secondary feature only if it doesn't interfere with any still camera function, but it seems that line of thought is alien in todays camera design, but we'll know more clearly how usefull it is as a semipro still camera when it's out and it gets reviewed in depth.
