40k's approach is better I guess.
You lose your new battleshock roll? Ok, you can't contest objectives or receive commands, but your nice painted minis are still there in the table.
I think that could be easier to think about the armies that will get just one box.
SoB, Sylvaneth, NH, FeC, S2D, Slaanesh, Kharadron, ijz/kb (?), gitz (?), Seraphon (?), Nurgle (?),
Reallistically, I only see Ogors and CoS 2 as big refreshes, fs idk, dok, tzeentch or obr, as armies that feel uncompleted just need an expansion like ironjawz and popular armies such lumineth or soublight could be nice with the Sylvaneth/nh treatment with 3-4 boxes.
Two new armies could fit.
Hm… no.
We have one mini (the shadow aelf from silver tower), a short story in broken realms with morathi, a mention as part of the aelven pantheon in a warcom article, mentioned in the hachette magazine Mortal Realms and in the Slaanesh book.
Apart from that, Malerion is an integral part of the story of AoS since it’s conception.
But I think this is not a competition about how many times time talk about who, actually chorfs have been confirmed by wf and Ulgorothis are missing from any hint, so I don’t expect them at all.
Supposedly, those leaks came before Adepticon, and most of them are being confirmed now by the Adepticon preview (index, weapon ranges), today's video (counter charges) and wf jr (spell lore, double turn changes)
