Lol, almost looks like a typo. on the http://www.google.com/registry/domains.html page they list .PROF, not .PROD

Also, the .PROF domain is not listed at iana yet (http://www.iana.org/domains/root/db/prof.html = 404)

Are any registrars offering registration of .prod's yet?

Doesn't look like it, per http://www.google.com/registry/ only .みんな and .soy are up for registrations.
