We're told that Canon is working on using a global shutter for the upcoming replacement of the Canon EOS-1D X. The hope is to get the camera to shoot at 30fps for still images, which would require a lot of upgrades and new technologies such as CFast.
What is a global shutter? (From Red)
“A global shutter controls incoming light to all photosites simultaneously. At any given point in time, all photosites are therefore either equally closed or equally open. A global shutter can work either by abruptly exposing and then obstructing all photosites at once, in which case it can be thought of as a “hard shutter,” or by doing this more gradually as a “soft shutter.” Since they have no moving parts, these are sometimes also referred to as an electronic shutter.”
I'll let the more engineering inclined discuss the likelihood of this technology for CMOS DSLRs on the forum. This comes from an unknown source, so take it with lots of salt.
