When are going to start getting information on Brooklyn DLC?

Season ends in under 11 weeks, so less than 3 months left and allegedly next DLC will be after that, have they revealed anything, has anything been hinted - anything? I truly hope it isn't just glorified manhunt missions but actually some game mechanic improvements etc?
Makes me worried that we've not heard anything at all - with ACS being delayed... not sure what to think at this stage then...
