"Just hotfixed the cost of Battle Pet Training to 10g. We still don't want newbie players but 100g was obviously overshooting that goal."He also mentioned Pet Battles achievements.
"Another note on pet battles, Taming Azeroth achievement is setup to complete with either Taming Kalimdor or Taming EK, you don't need both.This last bit of information is good news since completing both EK and Kalimdor can be tricky. Completing the EK achieve is easier for alliance while the Kalimdor one is easier for horde. It's not impossible, but it's somewhat of a hassle, especially if you don't have any alts on the other side.
Note that the display is wrong in 5.0.5 since the change was made via hotfix. Functionally, it will work though. UI is fixed in 5.1.0."

UPDATE: And another hotfix! Hooray for Tamer dailies finally resetting. :D
"We found the bug with pet battle daily's not unlocking. It's been hotfixed and they should work now, cross faction. Thanks for the reports!"
