While prices are falling, and probably demand is too, I still think demand for top notch examples of all morphs will still be there. Too many people think "Ooooooh!! A pastel for $100!!! I'll take it!!" when that pastel is a crappy example, and will brown out so much it will just look like a nice normal as an adult. Cheap ≠ quality, and quality isn't cheap, so while prices will fall, top notch specimens I think will still retain some value (maybe less, but still have value)
But here's just my guess anyways...
spider - $200-300
axanthic - $300-500
pastel -$100-300 (I think a killer pastel will still fetch some money. Too many mediocre ones out there.)
super pastel - $500+
pinstripe -$300
mojave -$200-300
lesser - $500
albino -$400-500
high contrast albino - $400-500
