Hardly. More test builds for various phones pop up almost daily on the UP repositories .. quite a few of which aren't bQ or Meizu (or community projects for Android phones). This suggests significant interest from OEMs.

They've done the right thing in delaying, rather than launching a half baked mess like Jolla did. There are certainly things I don't like about UP at the moment, but speed of development seems to have accelerated massively in the last month or 6 weeks, since they've now resolved most technical blockers.

bQ event is on February the 24th for the launch of their low end Aquaris. It's thought that they'll announce a higher specced version at MWC.
