All "sites" deliver luminance information. Only interpolation of the data can give colour. It depends on the RAW converter just how much luminance information is being extracted, some are better at that than others. And of course, interpolation between the sensel values play part in it.
But it is wrong to think that because of interpolation luminance information (or data) is half of that of foveon sensors, that is simply untrue and just shows a lack of insight in the matter.
Which again still misses the major point: the sharpness of AA-filterless sensors is mostly FAKE detail. That you can measure fake detail as normal detail and think you get a lot higher resolution is of course true. Does not make the validity of the detail higher, though.

So you're saying that an array of four (GRGB) sites, sensitive to a specific wavelength and simply discarding the remaining data, will resolve exactly the same detail, as an array of four sites that collect 100% of light, right? Even if a high-contrast transition (let's say, between a red object and a blue sky) falls on a green pixel and the "edge" gets interpolated? Sorry, but it's completely against my understanding of how the interpolation works and unless you could provide some link to back you up, I find your claims completely unfounded.
