IGN have posted a solid preview of Dragonshard, the Dungeons and Dragons RTS in development by Turbine. Several impressive screenshots help make a comprehensive look. Here's a snip:

Though some will undoubtedly argue with me on this, the most essential thing about D&D is the character class system. The abilities of the varied archetypes of paladin, rogue, wizard and so forth are rendered in Dragonshard even if things like ability scores and alignment aren't. While these heroes can be used as individual combatants, they're not like the tide-turning heroes in Warcraft 3. The heroes of this game share certain abilities with the squad of rank and file units they lead.

Much like Kohan or games from the Total War series, you'll command the regular cavalry, infantry and archers of Dragonshard in groups. While the groups don't have to have a hero leader, assigning a hero to a squad multiplies the power of the squad and the power of the hero substantially. A paladin teamed with a squad of knights grants massive charge bonuses while a cleric at the head of a group of archers allows the individual soldiers of the unit to heal themselves. Putting a ranger with that same group gives them fire arrows.
