How big will the new story line be?

I'm glad it's not an engine overhaul or something like that.

I really hope for a solid, comprehensive user-side editor and random map generation though.

I think KB would go down in history as the greatest of the turn-based heroic fantasy genre if only it gets something as good as the Age of Wonders 2 map/campaign design tools. The community would seriously get large fast and it would stick around forever.

The problem with these campaigns is they wear thin in time ... one always wants for more "map" content. It seems natural to allow users to make that content, and then there will be all the more excitement in official content because there is a healthy community. Also official expansions can provide larger modifications, item sets, units, etc. from the people who know what they are doing, which could be applied in a modular fashion.
