Consensus around here broadly seems to be that the next Lord Pack, expected some time around October, will be the final one before WH3 and its pre-order DLC are announced. This is based on the following comment from @Grace_CA
in the last AMA on reddit:
This came out before The Warden and the Paunch was formally revealed, though by this point everybody knew it was coming. What followed were a number of comments asking for clarification, which was not provided. Instead, we have all assumed that Grace meant the next two Lord Packs included the upcoming WatP. What if it that wasn't what she meant at all?
It's explicitly stated that this isn't set in stone and is subject to change. That could mean that COVID caused delays and hiccups for the CA team, and maybe a planned Lord Pack got scrapped. Or maybe it could mean that if WatP was a bigger success than expected there was a chance they might do another Lord Pack. Or maybe we just misinterpreted her and she wasn't counting the WatP in this statement at all.
To clarify, I am not saying we should expect two more Lord Packs before the WH3 announcement. What I am saying is it's possible, and if for a moment we set aside our assumptions about only one pack remaining, what does this possibility change?
To me, it means three things. One, it increases the odds of a DLC for DLC Lord Pack, as otherwise they might run a bit low on content. Two, it means three Old World Updates before WH3, assuming one comes with the pre-order. Three, it means an additional FLC lord.
In what other ways would this possibility alter our existing calculations?
