Just found this - didn't even know about it.

It's a 5-pack of Legends figures, in a battlepack of 3 Autobots and 2 Decepticons.

Autobots - Ironhide, Mudflap, Swerve.
Decepticons - Runamuck (finally in white), Sparkcrusher.

Sparkcrusher is a new name (to me), but I hope that Mudflap and Ironhide have some different colourings to them to the regular release Legends figures, otherwise some fans will be a bit upset about doubling up just to get the other 3 figures.

It is labelled as a US Target exclusive. It is unknown at this time if we will see this here, or when it will be released in America (should be within a month or two if this packaging pic has been posted up).
