You are right Andy.
The problem with RAW is, as you say, with every new camera model, a new beast is born. I wish the camera manufacturers could figure out a uniform standard for RAW instead of personalizing it to every model of even same camera brand. I remember that older DSLRs were had RAW (Some the only format available) in TIFF format. Of course that is not comparable to the modern RAWs.
I think it would be fair and right to add the needed plug in for major softwares such as PS when camera manufacturers make a new model, instead of suppling a very limited handicapped software of their own. At least they can make their own software compatible as a Plug In in the PS or like wise.
