Can one of the authors or playtesters leak details of (upcoming supplement)?
In a word, no. Authors and playtesters enter a legally binding non-disclosure agreement with Atlas Games. If one of them were to leak details about a product before it was published, he or she would be hung, drawn, and quartered. This question seems to come up occasionally on the mailing lists. It’s true that several Ars Magica authors are regular posters to the list, but that doesn’t mean they will let anything slip. Sorry.
