It would make sense, since gw wants to eventually separate the ranges so thousand sons are going to need a tzaangors kit separate from the aos one.

But I doubt that, I think this last note
>until then, rest well and don't let the nightmares get to you
is a subtle reference to the actual next kill team boxset

I don't want to kick the hornet of ritualposters and related shitflinging, but dark eldar do have a unit that contains beasts that are literal nightmares given form that chase down people
