Look, if they added in-back LCC, ie either by metadata GUI input mask (can be overlay in live view to select a favorite preset with a quick finger flip, e.g. SK43XL 10mm rise, f11) ... that would be a great, great addition to the digital back. If you could upgrade the SoC and have a lot higher efficiency, responsiveness and faster networking over WIFI, etc. ... then that would I assume give the backs another life line of 2-3 years where people could be "entertained" until Sony really pushes out a 200 / 300 megapixel sensor.
Hope they one day do a kick-ass firmware update again.
