HERO

On Elemental Hero Airman and Elemental Hero Ocean, it states that any card with "Hero" in it's card name, is used to calculated how it's effect is carried out.

The OCG uses E HERO and D HERO at the start of their applicable cards, so HERO would only work for those two. This is not the case with the TCG.

If this was left unchanged, it would mean that not only are all Elemental Hero and Destiny Hero cards covered, but any cards so far, with "Hero" in their card names, like Hero Kids. This is entirly open to speculation.
