Under Nokia's regime, there'd be half a dozen or more Lumia smartphones popping up in a year. Now owned by Microsoft, that seems to have cut that number a bit. That doesn't mean, however, that Microsoft won't be churning out new models. In fact, here we have rumors of two Lumia smartphones coming out this year but first making a stop at China's certification agency. Those two, which might either be the Lumia 750 or Lumia 850 or both, are still in addition to the Lumia 650 rumored last month.
