Dire Boar Animal Companion (re Orcs of Golarion)

[Robert Little]

So in Orcs of Golarion, there is several mentions of dire boar animal companions (for druids and mounts for cavaliers), but I can't find actual rules for them anywhere. Do the rules exist already or was that an oversight of the writers?

[Enevhar Aldarion]

I can't guarantee it, but I thought I saw in another thread that they would be detailed in the second Bestiary.
