Is Blizzard seriously not planning to itemize things for bear tanks?"
Because the druid kit does not rely on the defense stat nd takes much from core and universal stats such as agility, stamina, and armor, there does not need to be gear specifically tuned to druid tanks (although there is some). Instead, druid tanks roll with rogues and cats. This isn't a bad situation, and is about equal with the other classes. Warlocks, mages, and shadow priests roll together (more or less). DPS paladins, warriors, and death knights roll together (more or less). Plate tanks roll together (more or less). And healers... well... healers are just nuts and roll on anything that they need -- same with hunters. LOVE IT.
Remember, it's not about the gear, it's about the way your class interfaces with the gear.
