These are the real data you may be looking for.
A player that spoke to Live Support said it will be released in late December or in January if there still are bugs needing to be fixed first.
Pets: Shizune(neko) and Hayate(female ninja) both wind elementals. Shizune has Cord spell/something like that, so she's burstable.
Pet rebirth hasn't been announced, I am quite sure it will be implemented in V6.
Skill: Fatal blow. You need a kicka$$ party to get over it.
