Leica seem to be devoting more attention to the development of the M, SL and TL camera systems, and have paid less and less attention to the X line. The original X1 became the X2 and then X-E. The Vario has been discontinued and Leica stated that it won't be getting a new model. The X 113 doesn't seem to be faring much better with no upgrade in sight and no firmware upgrades, either.
Is there any sign of the X line developing further, or will Leica maintain the remaining models and then quietly drop them from production? This would be quite a shame as I think large sensor fixed lens cameras are useful and have a lot of potential.
