I have been in contact with Glynnis in the past months, and as reported recently, she went to the San Diego Comic Con to meet the Blizzard folks there.  She had been spearheading her way to get back her role in the past months.  Glynnis barely commented on the subject, but finally confirmed her participation in Starcraft II in her August newsletter released today.  I do not know how this affect our upcoming interview, or if she will be able to discuss certain details.
