I'm sure many did. I watched a B&H video with a factory rep stating that they are aware of the RAW compression objection. He stopped short of promising a change but he gave the impression that one would be offered. The question is when and for which models.
OK - that gives us a good reason for waiting for the MODEL AFTER THE NEXT
The next model's electronics platform should be just about finalised about now, and it might not be possible to do any mods, but the model after the next is probably under development.
The same A7R2 sensor may though quite possibly have a Nikon mode, so you could get lossless from it in a Nikon, without the stabilisation and other addictive paraphernalia
