Definitely hoping they release a kit for player created content, then. I want new stories within the same game setup, not more Baldur's Gate only adventures. After the first playthrough, there isn't much to be gained from the story, but the foundation of the game itself is what makes the potential so awesome. They did environments and combat and all the world building stuff so very well in this game that it would be awesome to have some way to keep experiencing the same toolset with new stories to keep it fresh. Having grown up with NWN, I don't really need voice acting to make a story fun for me...but then of course with AI being so prevalent now, creative people might figure out ways to get that done as well.
I guess I'm just really hoping they choose to go the route NWN did and allow player servers with unique adventures. There's an infinite world of adventure just waiting to be had...if we can just get the right tools.
