Most folks in the hobby are fascinated by newly discovered species or color morphs. Some of the recent discoveries are nice, but objectively, when compared with some of the frogs we have in abundance, they aren't really that much more attractive. Also, keep in mind that those types of photos are likely taken by professional photographers and of the best looking specimens.
Also, especially with the smaller species, you can only really appreciate their beauty when you have a nice close up with a quality camera. When I was selling some intermedius, I took photos and zoomed in on the individual frogs to post for sale. It almost made me have second thoughts about selling them. Up close, they are gorgeous. Honestly, though, in a thickly planted viv, with condensation on the glass, and someone like me who needs reading glasses within 2 feet of anything small, the differences among thumbnail color morphs isn't as dramatic as, say, the differences seen in close ups from talented photographers like JohnC, eos, and others.
Imagine if Leucomelas were only recently discovered. We'd go nuts over them and yet because they are so common and have been in the hobby so long, most dart froggers are pretty ho hum about them and other common varieties.
Unfortunately, the smugglers know this. They know that if they can bring in a new species or morph, that there are enough people who want the latest model to make it very lucrative to take the risk.
It wouldn't surprise me if some of the photos we see of new frogs are floated out there by smugglers to test the interest level by watching the buzz on the forums. They have the frog "laundering" thing down to a science. They check the data from those who discovered the frog, get the location information, and probably have a breeding group somewhere in Europe within months of discovery.
It wouldn't surprise me if both these new frogs have already been smuggled out. IMHO, I fear that if we oooh and aaaah too much, it will only encourage them.
