Was reading the threat from beyond spoiler and noticed "Sixty new cards, including one warlord, his eight-card signature squad, and three copies each of seventeen distinct cards bolster your forces in this expansion. You must vanquish all enemies of the Emperor in the Traxis sector, but in this war you will face Ork warbands, fearsome Noise Marines, and the might of the Eldar Wraithknights. Choose your faction and battle for the fate of the Traxis sector!"
Looks like wraith knight will be the first super heavy.
