Faster than you can repeat a surname, the James Bond games have disappeared from Steam and Activision's own download store. In addition, the download versions of the games 007 Legends, Blood Stone and Quantum of Solace don't show up on Amazon, though of course the disc versions are still available there.

The likely explanation would seem to be expiring rights to the 007 license, but the timing doesn't make sense on that, considering that 007 Legends was just released in October (and November on PC). We're investigating the matter, though not in the sexy, brutal James Bond method: we've just asked Activision about it.
