Segregated witness: When and how does it activate or when will this be decided?

Currently BIP141 saysThis BIP is to be deployed by version-bits BIP9. Exact details TDB.From what I can see the reference code still refers to BIP65 and not BIP9.Is my understanding correct? I'm asking as there are posts which say segwit 'Enters Final Testnet Stage' and am not sure how this could be final without the activation details confirmed. via /r/Bitcoin http://bit.ly/1MVSj46
