Good question, really.

Could be anyone of course, but I guess hoping for Nokia presence is to have something for the masses too; currently Nokia only cares for business-to-business market and has really given up on consumer market.

There's Withings of coure, as it's now incorporated into Nokia there might be some new developments on that front.

My personal belief is that if something new comes out in 2017 it'll be something like that, it sure won't be anything to do with phones or tablets; there just is no business there, no possibility to have enough revenue to attract Nokia to that market.
