I've been thinking about it, and the more I play these two games, the more I get the sense that IA is the test bed for Descent 3rd Ed.
Given the new minis game, and the skirmish mode from IA, I wouldn't be surprised if they went this route for Descent in the next couple of years. You could tie in figures to 3 games (descent, it's skirmish version and to the RuneWars), and create a lot of cross purchasing potential. Thoughts?
