If they do a seperate harlequin list, this stuff should come back.
I'm kind of ok with the solitaire not being in there - they're rare, even amongst harlequin troupes...
I'm just waiting for a harlequin troupe army list using the new rules...add in a few new skills and some exarch/dark eldar wargear (e.g a variety of masks and the terrorfex - harlequins always had wrist- and backpack-mounted grenade launchers).
Jetbikes, independant death jesters, and solitaires really belong in a pure 'quin army....
