Sony RX1 better than DP2 M

Does resolution even matter anymore? That's not meant to be snarky, it's an honest question -- cameras today are resolving detail necessary for good poster-sized prints. I still prefer the DP2X (yes, X) to the newer crop of 20+ mp cameras -- they can jam all the resolution they want into these cameras, but I prefer a clean image with attractive colors and crisp micro-contrast. But I don't print poster-sized images, way too expensive for my hobby.
