I hope Microsoft decides to target Google Now instead of Siri. Google Now provides so much more depth than a voice interface; Siri offers so little in comparison. Siri works well as a voice activated personal assistant (that I rarely see people use).
Based on search history, emails, and location Google Now provides information before you need to search for it. It happens to have a voice activated interface available. I'd really like to see Microsoft do more than creating a voice activated app for setting alarms and searching yelp with Cortana. The screenshot looks promising and the author probably made the Siri connection himself so I feel hopeful.
