DSLR mechanics question, idea.

Ok so here's my deal. Coming from a sony a33 (first camera besides cheap P&S), and now with a K30, I've seen things from very different worlds already. So I ask myself, with electronic first curtain shutters in many cameras today, mostly mirrorless and SLT, why do we need a shutter to begin with? This isn't even the biggest part of my curiosity.

Take video for example. The camera knows how to take 30 (or whatever #) frames per second as video, and the shutter is obviously not capable of that speed. So we are in LV, the sensor is constantly exposed, and the camera digitally snaps dozens of 2mp shots per second. Why can't my K30 do this 6 times per second and just use the whole rez? we can even tell it how long to expose each frame in video. Why is it my camera can do all this electronically for video but not in photos?

Is this just a way for the industry to keep us buying new gear? Shutters are often the weak link, driving repair costs or body upgrades. Any thoughts??
