I'm not sure if anyone ever confirmed this or not.. We know that they are reducing the cool down on our ele pets to 10 minutes, and we wondered if they would reduce the current glyph from 10 minutes to 5, they did! I'm on PTR now and i can put my fire ele pet down every 5 minutes! WOOT! It last for 2 ( if it lives that long ) so it will be available most the time! At least for every boss, and in PvP a lot!
