Yes. I agree.
The lack of third party RAW processing software support doesn't help as well.
Are you saying you can't process the foveon's RAW images with third party software? Because myself and most others who used it, did so with no trouble. I have not heard of a lack of support for the new Merrill sensor, if that is what you're saying. So that's news to me. You're saying Lightroom 4 cannot open Merrill RAW files?
Yes. I was talking about Merrill RAW files, Adobe has no support for them yet. However, previous generations of Foveon RAW are supported.
