Last week we heard the rumor that Nike was scaling down its FuelBand hardware team and shifting its focus to the associated software and underlying platform. Now CEO Mark Parker has told CNBC that the sports giant is indeed concentrating on software development as it looks to grow the userbase of its NikeFuel tracking system. Whether or not that vision includes future versions of the FuelBand remains to be seen, but Parker did say that Nike would be teaming up with other companies in the years to come.
