I recently picked up a new 2016. The first few times I rode it, I didn't notice any noise like this, but while I was out today, I started hearing this droning whine when the wheels are turning at low speed. I can also "feel it" through the footpegs. Once the bike gets up to road speed, I don't hear/feel it anymore. A few minutes before I started noticing it, I did hit a divot in the road kind of hard where a utility cover was. I should have avoided it, but the suspension seemed to take it ok. I guess I'm just kind of concerned that maybe I messed something up with the new bike. Or maybe it's perfectly normal. It's possible I'm just being paranoid since it's a brand new bike.
