Unispectral, Israel, Tel Aviv University-originated startup proposes to move sequential color imaging into camera modules. The claim is that switching Bayer filter for a sequential design increases the camera resolution by a factor of 4, and the low light sensitivity by a factor of 2. These claims are presented in Optics Express paper "
Sequential filtering for color image acquisition" by Ariel Raz and David Mendlovic. (David Mendlovic used to be the manager of Tessera camera module design and now serves as
CEO of Corephotonics.)

Older project info at
Tel Aviv University site says that they use a tunable filter for the sequential imaging and that "
Comparing with a Bayer scheme, for green the sensor provides 2 times more resolution, and for red and blue 4 times more resolution."
Thanks to WRWWCTB for the pointer!
