Word is ESPN isn't using their own announcers...this from
www.formula1blog.com: "Update: I did hear from the nice folks at ESPN that the broadcast would be using the F1-produced world feed including announcers who have not been determined yet, which is what NBC and SPEED used if I have my facts correct, and that there would be no ESPN announcers involved in the broadcast. Now this adds a different slant to the situation."
