that means nothing, the first-gen pixel was discontinued before the second-gen was announced too. and the chromebook pixel is hardly the only chromebook out there. it's a thriving product line, and the pixel series is a very very unimportant part of it.
Google has gotten worse and worse at this. It used to be that they would launch something right when they announced it. Then they would launch something invite-only when they announced it. Now they announce things without even having a clear idea of when or how those things will launch.
