Given the quality of these samples, I hope Sigma come out with a full-frame, 45MP (135MP in their terminology) Foveon sensor soon, with the same pixel density as their current 1.7x crop sensor. In a mirrorless system, it would be the ultimate non-medium-format landscape camera, optimised for low ISO settings. Just pair it with a few nice lenses (Leica with an adaptor comes to mind) and you're good to go!
