I hope they come out good. I actually quit playing 40k some years ago, told myself I wouldn't come back until plastic sisters. Looking forward to playing again.

Celestine came out not long ago, so I'm guessing they'll go with this design for the armor, hopefully. I'm guessing the repentia and penitent engines will probably get shafted though :(
