This forum is mainly for gamers to talk to one another, and while the Larian community management team do trawl it for feedback and bug reports, we don't often get direct answers to questions here ... though it's always a possibility.
I'm not aware that there have been any announcements about achievements, but if the info you want isn't made available at this Friday's Panel from Hell you might be better off contacting Larian support (you can find details of how on the Larian website) and seeing if they can tell you.
