Well yes, arrow functions are the magic ingredient.
But the point is that with them you can express custom control flows trough custom functions instead of built-in syntax without much of a loss of readability.
So we don't necessarily have to wait for ES7. We already have alternatives.
Some people have also built async from generators (yield) + promises. So that's another ES6 alternative.
