Point Grey video gives a sneak peek of Sony next generation global shutter CMOS sensor, the IMX250 (starting at 2:15 time). The new 5MP 2/3-inch sensor has a smaller pixel size, and a more effective global shutter:
Update: Michael Jacoby, Point Grey's marketing and the author of the company's videos, says in comments to the video "the IMX250 is a long long way from production but our testing shows it has similar imaging performance (quantum efficiency , dynamic range, low temporal dark noise) as the current Pregius sensors (imx174, imx249) and in some cases is better. Major differences is the smaller sensor size and smaller pixel size."
