Renegades & Heretics seems like a great candidate for Agents of the Imperium treatment. (Incorporating into a pre-existing faction, then -- optionally -- indexing, then codexing.)

Vashtorr included? Or, is it too early for the godhood or any new Soul-Forge representation? ^^'

AFAIK, the Ancient was listed in the massive 40k leak from Bolter and Chainsword of August-ish 2021 (the same one with unreleased CSM Bikers). Valrak has been rather spot-on but his info is not always consistent (e.g. he had been stating for a non-negligible time that one of the forthcoming CSM Lords would be Terminator-clad, and introduced uncertainty on the armour type later on; similarly, Brood Brothers Kill Team was meant to be Kasrkin-based).

Indeed, but there is almost always uncertainty. And there are better word choices for such circumstances.

Why should that be even relevant? Besides, there is a whole spectrum of physical features in humans, and I'm glad GW utilises the differences by introducing more realistic and less stereotypical forms. Don't present your speculation about the design process as an "unquestionable fact" if you have no insight or intel about the process. Oh, and sure, you know the conceiver is a "he".

Hopefully, they're reserving it for Morghur's faction, plausibly as the Utmost Mutation™ tier. An in-between aesthetic gradient in other factions would be welcome, although I appreciate the somewhat more hopeful aspect of treading the Path to Glory.

Or, one of them ascends and subsequently gets unmade by Abraxia with a steel chair, erm, mutating spear. After all, she hunts Daemon Princes.

New miniatures aside, this is the most intriguing part to me: Archaon--GHR "contract" renegotiation.

The Dawnbringers went too far and built a city on a Necron Tomb World.

On the Abraxia introduction, she will probably come in a set with Varanguards, Ionus-style. (Educated wishlisting as I'm still waiting, what, 8 years for the cavalry being included in a discount box xD)

I don't expect Khul before the drop of E4 if he needs to "kill" Vandus for the ascension. This will probably happen in a Dawnbringers 6 climax, so a spoiler level higher than "Saviours of Cinderfall". And then, Blades of Khorne might be one of the first battletomes after the launch-box factions.

Major design changes do not always occur (I welcome them, as Tzeentch approves). Same happened in the E9-to-E10 transition in 40k:

It was a dedicated one due to spreading the previews over several days. 40k E10 Celebration-style Preview stream was an irregular one -- this was split between the Battle for Oghram results (Tyranids there) and NOVA Open. Mind that Dominion Celebration was a follow-up to the multiday Fest 2021 which announced AoS E3 (there was no Adepticon teaser) with a different approach to faction focus and content reveal. At least compared with Leviathan.

I forecast there will be an online Fest-style preview, like in 2020--2022 (IIRC). Adepticon seems quite packed with the number of games-settings sporting some content, and GW likes to stretch the hype. Thus, I don't expect a different treatment than 40k E10 preview at the event (full cinematic trailer, a non-character model per faction, discussion about forthcoming changes).

This happened at Warhammer Fest, so yes, it had one.
