Multiple sensors, stuff like Google "night sight" and all that fake bokeh are impressive. But compared to the benefits from liberating the optical path from the burden of minimizing distortion and vignetting they are little more than lipstick one a pig. Simplified optics improve the source signal, some hard trade-offs that defined camera design for more than a century have been blown wide open by a simple 2D convolution.

Admittedly, multiple sensors also create more/better source signal to work with and unlike optical path simplification it's an improvement that can be repeated over and over again (just add more), but currently it's main importance is that it is something for buyers to see, without diving into the subjectivity-infested depths of image quality comparisons. I have no doubts that a bad multi-sensor would sell better than a good single-sensor.
