No just CD's at this point. It is DVD BluRay drive so we will be adding features in the future but I do not believe Sony allows access to SACD bit streams.
This has been mentioned before (i.e. new features); I am very curious what that might entail. SACD will never happen, as you mention above. But even DVD and/or BD ripping is a challenge, from a legal standpoint. Some countries have fair use laws that would allow this, but neither the US nor Canada are one of these countries.
Direct DVD Video/Audio and BD audio playback would be interesting, using the MM UI to control playback, even without a display connected, if you can acquire the chapter titles and present them as a list of tracks, auto-selecting the mandatory 2-channel PCM track required by those formats. I have a BD player and an LCD panel in my head-fi stack just for this purpose and I would love to get rid of it.
Could be very cool if it's done right... anyway, anxious to see what's next with the BOT-1.
