The 1.2 patch is all about crusade tweaks, yes. They simply want to polish it so it won't stay as a slightly better analog of sea combat of Deadfire.
As you can see, crusade tweaks are in the last place. Well, I'll take whatever they toss at me, there will be like five new big patches and two editions after that.
There is a huge amount of tweaks for Crusade, but there's a ton of other stuff as well. You'll see soon.
