[Leica] Up-resolution with PS Enhance and with Gigapixel

My feeling is that a Qx with a 24mm f/2 lens and 100Mpx sensor (x = 4? 5?) would be all I’ll ever need from now on. That would give an EFL range to 150mm or so with enough pixels to put a 13 x 19” image on my screen or wall. By 2030 I’ll be lucky if I can see to compose a picture or view a print!
