I heard from battle director Morimoto-kun that if you have your pokemon hold the item "Red String/Destiny Knot" and bring it to the Day Care, FIVE of your two pokemon's innate "Abilities" are passed down!
Basically if you have a pokemon hold the "Red String/Destiny Knot" item, you can pass down up to 5 IVs from both the parents.
Currently in the process of confirming if this is true or not, but this may make Perfect Pokemon *MUCH* Easier to acquire.
*EDIT:* I can indeed confirm this works. Instead of inheriting 3IVs from the parents, the resulting Baby inherits 5IVs. Others are free to test this as well and share results.
For those wondering where to get the "Red String/Destiny Knot" item it is in the Cyllage City Hotel from an NPC in the second floor.
