The Sorceresses of Diablo II will not be a featured class in Diablo III.
A rebellious woman who has wrested the secrets of magic use from the male dominated Mage-Clans of the East, the Sorceress is an expert in mystical creation ex nihilo. Though somewhat lacking in the skills of hand-to-hand combat, she compensates for this weakness with fierce combative magic for both offense and defense. Solitary and reclusive, the Sorceress acts based on motives and ethics inscrutable to most, and sometimes seems capricious and even spiteful. In reality, she understands the struggle between Order and Chaos all too clearly, as well as her role as a warrior in this battle.
This is just part of the material available on this topic. The Diablo2Wiki Sorceress article is available in the Diablo 2 wiki, which has a specific Diablo I and Diablo II focus. A lot of information unique to the first two Diablo games is available there. You can find it here:
