It's pretty much already been said, but maybe not quite in this way, so I'll say it again anyway

I think that the increasing ambiguity of genetics in a given animal, coupled with an increasing appreciation for "good quality" specimens of any given morph, will push towards a trend of animals being priced based more on appearance and bloodline and less on the morph(s) it carries.

I don't think we're at all far from the day when an exceptional looking bumblebee from top bloodlines commands a reliably higher price than a muddy brown super spinner blast.

So to address the OP's question -- I think that a brown, spotted, kinda poopy-looking snake that definitely carries ABC genes and "might" carry XYZ genes might be hard to sell in the distant future. However, a glowing, stellar, knock-your-socks off thing that probably contains this and definitely contains that will likely continue to be worth the asking price.

And yeah I agree -- it seems like a lot of these 5-6er combos all end up looking like either a faded silver snake or some sort of pastel lesser spider thing.
