Opinion, as always, are different. Counting the ''likes'' received for the idea of a 12Mp sensor, I can thing that's almost fifty-fifty.
About using JPEG instead of RAW, IMO, that doesn't count at all. It's an image. Period.
From my brief experience with a Canon D1X and a Canon 400/2.8 with OS, I thing that a OS shift system can be done, but with completely new algorithm, with in lens computing chip, and a lot of testing. And in this way, the image shift will be able to be applied by any manufacturer, including Pentax for his 645 series. But things are very complicated, because every lens (algorithm) must be calibrated for two different kind of sensor, FF and APS-C, with the single exception of Pentax 645 lenses. Some questions still remains. Can such a powerful CPU be placed and used in a lens? It is practical, and economical?
My opinion is no. Also I don't think that we will see a software upgrade which will make ''old'' cameras, like K-5, K-5 IIs (which I have), or even K-3, upgraded to this sensor shift systems. And not only because every manufacturer wants to sell new products, a normal desire from almost any point of view, but because, it could be difficult to translate coordinates given by today mechanism in SR, supraimpose them over some new coordinates, given by the need to move the sensor only one pixel, or even half, and make a coherent movement of the sensor. Even if we cut the SR correction function, and we let only the sensor shift, did we know if the electromagnetic system involved is precised enough to move the sensor exactly in the ''old'' cameras?
I said that to upgrade old cameras is not in anybody interest. Yes, for today, maybe I will like to see that Pentax is giving me a new and extremely powerful tool for free. But if this come with a major loose for Pentax, which can bring the firm in the situation to bankrupt, and never make new and advanced products, I'd better pass. It's my own interest, yes, a longer term interest, to keep this firm alive.
