I oppose publishing the current draft. 

There are two unresolved issues still being discussed on the TLS mailing list: 
 1. non-extension signaling for older versions (SSLv3 and maybe TLS 1.0)
 2. explicit vs implicit addition of old verify_data to the PRF (also known as fail-unsafe vs fail-safe)

I think the WG is converging, and that a couple of more weeks of discussion may lead to consensus. 

I agree with David-Sarah Hopwood that a last call (WG or IETF) is still premature.
