However, according to Mania there is a rumor going around which speculates that bite might be changed to become much the same as claw. A result of this would mean that any previous attempts to determine hunter pet DPS will have to be looked at again. Wolves might actually become viable pets again. Hopefully you managed to get a ghost wolf while you were able to do so. Owls and bats would probably become more mainstream as raid debuffs as well.
There's also a list on the EJ forums displaying some new pet skills. Keep in mind that some of these might actually be NPC or player abilities instead.
Please note that the "pet type" below is the speculated type most likely to be able to train the listed skill.
Smack (Rank 9)
Pin (Rank 1)
Swipe (Rank 1)
Rushed Assault (Rank 1)
Tendon Rip (Rank 1)
Spore Cloud (Rank 1)
Dust Cloud (Rank 1)
Serenity Dust (Rank 1)
Bad Attitude (Rank 1)
As you can see there's a few options which might appeal as interesting to WotLK hunters. Keep in mind that no data is final, or confirmed in any way. At the same time, anything is possible.
Flash, security alert
I need to point you out this post. The older Shockwave flash player has a major security issue. Update it here. The fix is already some weeks old.
