Wii Fuji use a normal sensor for next X ?

I could be wrong, but I see x-trans as the start of the post-Bayer era. It's only a matter of mathematics to get the image out of the sensor. Once that is solved and there are no impediments to using x-trans, more camera makers will start experimenting with different sensor arrangements, as a way of differentiating product and making people think their existing equipment is obsolete.
