The SCE side will pretty likely look like this:
Judicators, Celestant and Azyros/ Venator (I think the latter) will be renewed. Heraldor and Vexillor will fight for a spot. We already have a Vexillor, so probably the Heraldor will be the winner. Thats 4. We have one Castellant from Callis and Toll, another one? 50/50. Paladins? I also think they will be gone, but it is weird, they are quite iconic. The rest is sacrosanct, that is 100% gone and Whitefang teased us that Gavriel won't survive the Hammerhall siege.
If all the above gets renewed, it is 6 kits. Last year the follow-up wave had 5 kits: Warhammer Preview Online – Dominion Celebration - Warhammer Community (warhammer-community.com) so very likely Paladins and Castellant (and maybe even the Heraldor) won't make it. So IMO we have 3-4 kits pending to be renewed (as much) from that list.
