Well, this got a whole lot more interesting if this is true :

Plastic Jester and Seer should be bringing up the rear of this release. Seeing how they have miniatures, they are the ones without IP risks, while Solitaire, Skyweavers and Starweavers (which also builds a HS alternative) come first.
This might well be a 4 week release, the largest since .. Orks or Space Wolves I believe?
Hope all that is true, sounds like a much bigger release than the Militarum Tempestus (the closest thing to compare too) and would give them a decent amount of choice for a minidex.
