I don't think we get any more content patches, but I wouldn't be surprised to see hot fixes and bug fixes. On the other hand, the farther(further?) their dev code changes beyond patch 9, the more likely it breaks existing content, so maybe not?
I think it would be wise of Larian to not touch the Early Access content - but rather start to trickle out information at various events and a Panel From Hell.
- XBox announcement.
- However many other companions there are at launch.
- Any secret races or classes that they might have been working on.
- Multi-classing if it is going to be included at launch.
So on, so on. They can tease stuff without actually putting it in the game to keep the interest high.
