It's about time! For those waiting I'm sure this is a move in the right direction, however with some of the things the iPhone can already it's noticeable that some integration with Health is limited. Hopefully an update with come for the Nike Fuelband app today as well or soon. Currently with the Nike + Running app it can write fuel into the dashboard for you, but for those that use Nike Fuelbands I'm sure you'd like to see fuel for the whole day and not just during a running session.
Time will tell how much further Nike will integrate into iOS!
