An anonymous tipster has sent World of Apple the following section of code from within yesterdays iTunes 7.1 update.
"4309.161" = "Are you sure you want to sync games? All existing games on the Apple TV “^1” will be replaced with games from this iTunes library.";
"4309.162" = "Are you sure you do not want to sync games? All existing games on the Apple TV “^1” will be removed.";
"4309.163" = "Syncing games on “^1”…";
"4309.164" = "Some of the games in your iTunes library were not copied to the Apple TV “^1” because they cannot be played on this Apple TV.";
"4309.165" = "Some of the games in your iTunes library, including the game “^0”, were not copied to the Apple TV “^1” because they cannot be played on this Apple TV.";
"4309.166" = "The game “^0” was not copied to the Apple TV “^1” because it cannot be played on this Apple TV.";
"4309.167" = "Some of the games in your iTunes library were not copied to the Apple TV “^1” because you are not authorized to play them on this computer.";
"4309.168" = "Some of the games in your iTunes library, including the game “^0”, were not copied to the Apple TV “^1” because you are not authorized to play them on this computer.";
"4309.169" = "The game “^0” was not copied to the Apple TV “^1” because you are not authorized to play it on this computer.";
"4309.170" = "iTunes could not sync the game “^1” to the Apple TV “^2” because there is not enough free space on the Apple TV.";
"4309.171" = "iTunes could not sync the game “^1” to the Apple TV “^2” because the game is corrupt and could not be read.";
"4309.172" = "iTunes could not sync the game “^1” to the Apple TV “^2” because the game could not be found.";
"4309.173" = "iTunes could not sync the game “^1” to the Apple TV “^2” because an error occurred (^3).";
"4309.174" = "iTunes could not sync the game “^1” to the Apple TV “^2” because an error occurred. ";
World of Apple is unable to confirm how true the above section of code is but it certainly points at gaming on the Apple TV.
