BotCon 2013 Souvenir 2-Pack Sandstorm and Electron

We've known for sometime that Sandstorm was one of the BotCon 2013 exclusives. We now get to find out who he is paired with. The BotCon facebook page shows us Sandstorm and his 2-pack partner Electron who is a repaint of Generations Sergeant Kup with Machine Wars Hoist's head. They are seen in this picture along side Machine Wars Thundercraker and Mirage.
