In the Bloomberg interview, Parker specifically stated that "I'm actually quite bullish on our relationship with Apple. As you know, Tim Cook is on the Nike board. We're - we've worked - I worked with Steve Jobs a long time ago when we introduced the Nike+ for the very first time. So as I look ahead and what's possible between Nike and Apple, two as you said, amazing brands."
Parker added that "Technologically we can do things together that we couldn't do independently. So, yes, that's part of our plan is to expand the whole digital frontier in terms of wearables, and go from what we say is tens of millions of users. Right now there's 25 million Nike+ users, but to hundreds of millions."
