Even if Sandfire was an actual morph at some point in time, personally I don't see it as one because it is so over used. I see it more as a company. Everyone that has an orange-ish colored beardie says it is a sandfire, and plenty of pet stores say they sell sandfires too, when they have no way of proving their dragon's genetics or where it came from. IMO the majority of people who claim they have sandfires are trying to put a "special" name on their beardie... It's the same way with German Gaints. A lot of people and breeders say they have GG beardies, but they don't grow much bigger than the average dragon.
As far as I'm concerned, they are just yellow/citrus/red morphs. It's like calling a dog a "doodle" when it is just a lab/poodle mix: A fancy name brings in more money. Not that I really care though... I'm not too much in to the whole morph thing. Normal morph dragons are just as special as the rest on 'em. :wink:
Just my opinion.
