Antares Auto-tune Realtime Advanced Trial

I have and love many of the UAD plugs (including the uad original auto-tune), but I'm struggling to understand exactly what is improved in the 'new' auto-tune. (Maybe that's useful feedback for the marketing team).
Does the newest version now have what people in reviews say is missing? (graphic mode, formant, etc.)
Does the newest version pitch-correct 'better' (more naturally? more realistically?)
Does 'improved workflow' mean simply cosmetic ui changes?
Since there doesn't appear to be an exact one-to-one match with the versions listed on Antares own site to answer it that way either...
Enlighten me?
Thanks!
