On the Apple watch nike+ , can you use other watch faces or are you limited to the nike ones that come with the watch?

If read pretty much every piece of communication written about the Nike+ watch and some pieces it implies that the Nike features are just an addition to the standard features but other pieces imply that the Nike watch faces are the only ones available.

It would be nice to know which of these is the truth.

My hope is that the Nike+ watch comes with all the standard watch faces AND the additional Nike developed ones.

Anyone know what the reality is?

Many thanks
