The new OMD EM5II ?
#12
"theoretically" sensor shift does also require a static camera - what it is doing is moving the sensor about a half pixel or so (this quantity is arbitrary) and re-exposing the image then using the data from both of those exposures to mathematically undo some of the aberrations of the system.  It counteracts optical flaws well if they are on the order of 1px in size, though often they are far greater, but also helps increase the spacial resolution as you effectively get something very similar to full color information for each pixel.

 

In practice computers can automate everything and work quickly enough that it is not such a big deal - it is analogous to the increase in rolling shutter when using an electronic shutter vs a focal plane or other mechanical shutter.
