I expect nothing especially, we’ll see what they will bring in the upcoming weeks.
I’d prefer the game being more polished, with bug fixes and tweaks over new content, at least for a little time 
That would be a huge mistake imo 
They’re busy with Project Fantasy and 007. Remaking a brand new game with new mechanics and whole new team to work on it would only complicate things at the moment.
Meanwhile, there’s still enough potential for HITMAN: WoA to be expanded way further than it actually is through new content 
Not only cosmetic packs, but mostly new maps, missions, freelancer stuff…
