Yes, I hope they do. Not only would many collectors (and kids) who love knights love to have civilians to incorporate in their stories, castles, and villages, but it would reach a whole new market of people (like me) who aren't into knights at all but would enjoy these civilian sets, and probably end up getting a few knights to go along with them.
Very true. I like the soldiers too, but theres not much point in having soldiers and knights if they have no one to protect and fight for.
Seeing how modern civilian sets are very popular, I can't see why medieval civilians wouldnt be.
Medieval theme might be a difficult theme to collect anyways though.. aside from the limited amount of civilians and high price of medieval houses, theres new heraldry released all the time, and many of them are just on a single clicky. And sadly there often seem to be as many knights as soldiers released which kind of messes with the balance of power. From store sets it would be difficult to get more soldiers than knights.
It was the main reason for me to want the siege tower back in the 90's. It had five soldiers and only one knight.
Then again I also really wanted the king's court set since it added all kinds of interesting medieval clickies aside from the two soldiers.
