Seriously, this is so dumb. "Random" is being used in the consumer-friendly way, and in a reasonable way. In actuality, you are right - it's not random. But, generating true randomness is very difficult. As someone with a post-graduate degree in statistics and experiment design, I actually know a lot about this - my guess, more than you. In fact, many argue that even programs like Excel or statistical packages like SPSS don't generate true random output. Random should unpredictable, and anytime you introduce a formula to generate the output, the true randomness of the output is arguably questionable.

So, would you prefer Fuji put an asterisk next to the word random with a long-winded scientific caveat?

So dumb. Really.

Fujifilm keeps reffering to the X-Trans sensor's layout as random. For example:

"The unique random arrangement of the [X-Tran's] colour filter array is also highly effective in enhancing noise separation in high-sensitivity photography."

This is nonsense. Anyone who looks at the X-Trans sensor can see that it is made up of a repeating/ pattern of RGB. In other worse, if you see one unit (pixel) of the sensor, you can "draw" the whole sensor, over and over and over again. If the sensor were truly random, you would not know what the next unit would look like. The X-Trans is not at all random, it just has a different layout than the Bayer pattern.
