Yes, I plan to setup a preorder of the assembled v3 hardware for $30/shipped worldwide. The SSOP PIC is widely available, so leadtime is 3 weeks after the preorder ends (but should be closer to 10 days).
The V3 PCB is slightly smaller, has 1 less part, and the SSOP PIC is a few cents less expensive, so it might be ever so slightly cheaper already, but only by five cents or so. If there were a lot of interest (80+ early commitments) I might be able to negotiate a volume discount and lower the price more.
I'd really like 10 firm commitments before I put the deposit on a preorder. I also plan to do a preorder for my first monthly project in September, and I don't want to have a bunch of unsold Bus Pirates to contend with.
Anyone who'd like in on a preorder of Bus Pirate v3 can post a comment in this thread. I'll reply here when I setup the preorder.
