Seems like a lot of prototype images are still in use, even Adidas' YouTube video yesterday is a prototype design. Everyone who bought one has branding on the upper so far.
Got my Sesames from Asphalt Gold today and they were definitely using prototype images on their store. Looks like all the models out there will have the logo on the leather, not the sole.
I managed to purchase with OBD last week but despite the Paypal payment, their site told me the transaction was still 'pending'. Doesn't show in my orders now, not sure if they removed it or it's a bug, but I'm yet to hear anything back off their customer reps. Haven't refunded me or anything.
They're up on asphaltgold now, they seem to have the ones without the logo on the leather.

Some still on Animal Tracks although it has the logo on the leather

Running a whois on the domain tells me it isn't the same people that do the YeezySupply site. It lists the owner as some no name freelance designer (https://www.facebook.com/CeziHD). So, I wouldn't trust it just yet. Certainly not with your money or passwords you use anywhere else.
