Looking at the diagram below, it seems to show light from one microlens being defracted to an adjacent pixel. That gets more light to the adjacent pixel but isn't it going to blur the image?!?

The centre pixel on the right (W+R) seems to get white light from the centre microlens and red light from those on either side.

Compared to the Foveon technique used by Sigma (where the colors are separated inside each pixel), this one would yield lower resolution at the same pixel count. But it wouldn't lose resolution compared to a Bayer sensor (the one labeled "Conventional" in the illustration) with the same pixel count. In both cases (Bayer and micro color splitter), each pixel of the final, "demosaiced" image, has to borrow color information from neighboring pixels. Furthermore, the sensor industry doesn't seem to have any difficulties increasing the pixel count as desired, and the higher per-pixel efficiency that this technique promises makes such an increase quite reasonable. We can have more pixels than we used to at the same per-pixel noise as we have now and a choice between better resolution (at lower ISO) and lower noise (at higher ISO), by trading the extra resolution for lower noise as desired.
