From what I remember back in the pre-preview (Blizzcon?) they are removing "Class-Specific" stats from weapons and replacing them with interesting mechanics, like the ICC weapons.
For example, there will be no strength 1h'ers. There will be no Agility 1h'ers. They will all give AP, Stamina, and whatever else they fit on there, either procs like Bryntroll or raw stats like Crit/Haste/Hit/Expertise. Thus, 1h'ers are Combat Rogues, Fury Warriors, Frost DK's, Shamans and 2h'ers will be Arms and Fury, Blood and Unholy DKs, and Ret Paladins. Just like casters - I don't think there will be Int on caster weapons, as they will grant extremely high +Spell Power so that they can be as big of an upgrade to casters as they are to melee, without breaking your mana pool.
