For sure.
I'm so excited about the palmetto stuff, I just wish hets weren't a couple years away still! The first time I saw a palmetto, I just fell in love! It kills me that some people (even Brian Barczyk!) seem convinced all you can do with the morph is just change the eye color or get all red or gray speckles. You never know how some genes are going to interact. There are a bunch of palmetto projects out there that are gonna start hitting their targets really soon. Sure, diffused might have been kind of a bust (at least, it seems difficult to tell if they are diffused or not), but there are tesseras in the making! Stripe and motley! And fun colors too, like butter and salmon snow!
I have also been told by breeders (particularly in Europe) with high end projects that even if something hasn't been done, "the hets are out there"...as though there aren't THOUSANDS of morph combos yet to be seen or even dreamt up! Any breeder has the potential to make something unique (even world firsts!) if they think outside the box enough.
