Taking into account the recent events reg the Ransomware attack and breach of security. I am not sure if they will be able to release it this month. We might hear some news in next few weeks reg and delay for this update.
Let's just hope they add additional meaningful content in the game thru DLC.
Expansions, I have no doubt will be big.
But the free DLCs might just be additional hair styles, alternative looks etc.
I don't think it was limitation of writing, or how to reconcile it. I say, CDPR writers are one of the best in the industry they could've pulled it thru. But I certainly think that time was a limitation due to which they cut it or skipped over it.
The main story is not going to change now. And there will be no updates regarding how your choices affect the world.
But maybe in New expansions they can introduce a more flexible story with more elaborate choices and consequences like Blood and Wine.
