So based on what has been mentioned & the current space in the BoG I recon alot of ideas have either been dropped from the game or we may see a possible expansion of the BoG. Because from the info we have we have lost 3 slots in this coming update, Client, Baron's Wife & Daughter.
And we still have Qetesh, so dwarf & pets isn't looking like an option anymore (even though the dwarf blacksmith exists & looks like it's got a home sized space in the back, he has a lad sp mebaey a daughter-in-law

) so mabey Tinkerer is leaving the option open. Also the pets were in the pole...
I dunno. I hope Tinkerer finds a way to add these characters.
