Who Is Our Mystery Microsoft Interviewee? [UPDATE]S

Among the batch of interviews we have lined up for E3 with top game developers and captains of industry, we have a mystery interview today with someone important in the world of Xbox.

UPDATE: It was Phil Spencer, their head of internal game publishing for Xbox 360. No one there could recall why it'd been a secret.
