Sony Moves High-Speed

Sony Semiconductor CX-News Vol. 43 presents CMOS sensors capable of 60fps speed at full resolution, with further plans to achieve few hundreds frames per second speed. Not much details are given, except of co-developing a supporting DSP which is promised to "take full advantage of this performance". No word on the sensor resolution either.
One of the features is "Multiplane Addition:

Recently, the number of users who want to shoot indoors or evening/night scenes cleanly and preferably without flash has been increasing. Thus cameras that boast camera shake correction or high ISO sensitivity have appeared in the market.
These products adopt either camera shake correction functions in the lens or high-sensitivity image sensors.
However, there is another way to achieve camera shake correction and higher sensitivity (higher signal-to-noise ratio).
This method consists of continuous imaging of the entire frame at 60 frame/s, and using this increased amount of information in the time direction to create a single high-quality image. This can be implemented in a total camera system that includes a camera DSP. For example, if someone applies multiplane addition to several images that were captured at 60 frame/s, an image with a signal-to-noise ratio several times better can be acquired. Also, a high-speed camera shake correction function can be implemented if images are stacked while applying camera shake correction to each image. This function can make it possible to capture bright, camera-shake-free images even without an inlens camera shake correction function even in slightly darker environments where camera shake can easily occur, such as school festivals, children’s plays or presentations, or indoor events.
"

Here is a demo of the new camera shake reduction feature:
