Martin, I confess that my remaining GXR kit fell out of rotation in the last year, having made room for an X-E1, X-100, and a DP2M, but your thread inspired me to pack it today with the 50 2.5, and over the weekend with a couple of the modules (+ maybe 50 1.5 on the M/module), + the GR since they handle/shoot the same way. That GR/GXR haptic complementarity was, for 2 years, the basis for all my work and practice, and it still produces splendid results for me as a BW shooter/developer.
I certainly don't have the desire or the budget to Leicafy with any of their non-M digitals. The M5 (and Hexar RF) are FF enough, and I can afford to keep at bringing my BW/chrome film technique up to the levels of my digital work with APS & m43 (I really need to focus on mastering 1 or 2 emulsions for measurable, stylistic consistency--but that's another topic).
The Monochrom is the one digital M model that compels me to think of selling off a cabinet of less-utilized users/collectibles, but there need be no rush where's there's insufficient Robert-$ (photo-revenue + disposable income). In a year or two or three, FF choices in smaller cameras should beit will be clearer
Also, a foolishly optimistic bit of me hopes that Ricoh will update the GXR's modular approach to FF/mirrorless, maybe rebadged as Pentax, with a built-in EVF, and not just an M-module, but why not a K-module, an OM-module, an AR-module, a CY-module? Surely there are enough adapter manufacturers now to source different mounts to harness to the same sensor. Just a daydream, of course, but sometimes daydreams evolve into real stuff...
