Here's the Video where Bonnie had been asked a question about their collaborations with Microsoft specifically. Her reply seemed as if she was trying to dance-around an NDA of some sort, as she tried to avoid naming specific names... But she said quite a lot regardless.
It starts at the 15:37 mark and goes for about a minute or so. (and, as you can see, it was actually You, Steve, who was kind enough to post the video for us in the first place!)
