Diablo III Character Class Predictions

GameSpy has dreamed up some predictions for what the other three unrevealed classes might be in Blizzard's Diablo III.
...we're going to take a shot in the dark and propose that in Diablo III, the conflict has been escalated to such a degree as to necessitate interference from a higher power. Angelic characters would be a great fit, as the angelic host has been a big part of Diablo since the beginning. From the fallen angel Izual to the renegade angel Inarius, and even the sword-swinging archangel Tyrael, there's plenty of room for introducing an angelic player character class. Heavenly powers based on light and swordplay would be unique, while still fitting into the world.

The Seraphim will feel at home exploring Cathedrals.
The Angel class (let's call them Seraphim, to avoid controversy) would be heavily armored, and would swing a big sword, clearly defining a role for itself apart from that of the Barbarian. Summoning angels from above to swarm the battlefield as a top-tier ability could be great fun, and the opportunities for Seraphim-specific class quests abound. Kill demons, kill more demons, and bring some light to these dark times.

Personally, I don't think Blizzard will take a page out of Sacred's book. They'll go with something unique.
