If you watched E3 this week, you could not have missed the tablet and phone integration Microsoft will release with their Smart Glass technology. Google it if you missed out.
Let's kick off some great ideas on it's uses in GOW.
My ideas relates to spectator mode. The tablet would serve as an overhead map view showing the position of all the players. When the tablet user clicks a player, it would switch to that persons first person view. Alternatively, there would be camera buttons on the map (tablet) you could click for standard in place angles. The Xbox controller would be held by a second person to quickly move the camera around as desired during tournaments or whatever.
Anyhow, this could allow producers to make video game ternaments engaging to watch with such flexibility.
