Well it was inevitable that ravenous fans and journalist-types would begin to dissect as much as they could from BlizzCon about Diablo III.
Even the majestic talent tree of the Wizard has been raided to reveal the three branch types, Storm, Arcane and Conjure. Obviously Blizzard is likely to prune here and there.
Shacknews is the shameless molester of talent trees when it comes to Wizards, but since they've already comited the act there's no sense it shying away from what.
A new Rune system allows players to further tweak their talents in combat like say adding a multistrike rune that would then amp up abilities to, well, multistrike I guess.
