The fanboys are sad that OS X Leopard is going to be late, so in the meantime, here are some fresh screenshots to keep em held over. There, there, it'll be ok.
These are shots from the latest build seeded to developers, 9A410. Charming name aside, this evolution of the beta unifies the UI elements, ditching the now aging brushed aluminum window borders, along with the interesting Finder sidebar icons. Check out a few of our faves, but there are tons more at Thinksecret.
UPDATE: I also like Leander's take on the low probability of these being real, and the logic behind that reasoning.
UPDATE: Linked to Images from Thinksecret's gallery, without any of the suspect images.
