Known Facts about Shattered Heart
As Mod Maz explains, Shattered Heart will be a new skill update that will tie in with all non-combat skills. He states that when you are training skills, such as fishing or agility, that you should "keep an eye out for interesting things appearing in your inventory."

It appears that Shattered Heart is NOT the highly anticipated new skill, but rather an update that will apply to the current skills.
