While evan is going to move away from the masternode model (supposedly).
Is there any evidence of this? I've never heard anything about it.
He said he is going to move the anonymization on to the protocol level so mixing at the masternode level is not needed anymore. Masternodes will however do the work of quorums i.e. instant transactions (which will be on by default iirc) and decentralized API.
When and where did he say this?
Here, let me Search Function that for you.

18 months later, that promise remains broken.

Actually he decided to drop the ring signatures in favor of Darksend/Mixing because of blockchain bloat 10 days later.
