What do you think is more likely a Definitive Edition with cut content restored and or fixed down the line when the have time to do so or some kind of Expansion/DLC to expand on the existing game like more stuff fans want or Larian just moving on to make another game/project ?

I'm not sure why they cut the content that they did really in the first place.
maybe it was just content they couldn't finish in time for release so they cut it to save the time but knew it may cause problems later so having to patch the game like they have been doing ?
