Scout: they lowered it to 8 dollars a game this season.
In addition, they've already been running a service for the Euro 2008 qualifiers. Those they've had an individual price of 6 dollars I believe, but they also had all-day packages for 8.
I'll put it this way: I doubt it will be 3 dollars when the service comes to America (at least not on a per-game basis). Maybe, however, on a complete package basis, it could be close to that.
