I think they said that they are planning to integrate all kinds of anon stuff. And then I asked myself whether mixing up those technologies even makes sense or whether that is just done and used as an advertisement slogan. Anonymity has to make sense mathematically, and that's the point where I doubt that they really tried to figure out what the best solution is for the purpose they are trying to pursue.
Could you give more details about which "all kinds of anon stuff" you mean? This project combines 2 technologies, Tor and Ring signatures. Nothing more. OBFS4 is an obfuscator to hide the Tor traffic in countries (or corporate networks) which are blocking Tor. The mid-term plan is to migrate to using ring signatures by default and using RS tokens for PoS.
