We are going to throw this one up as rumor. According to DigiTimes and Industry insiders, "Google Inc is cooperating with Samsung as its primary production partner for the launch of its second and third own-brand smartphones."
Keep in mind folks that DigiTimes has missed the boat on more than one occasion, and this is only one source. If the decision on the next manufacturer has not been made yet, you can bet it is going to happen very very soon. We'll keep our eyes peeled for reliable information that will verify the veracity of this rumor. Does it matter who makes the next Nexus, or is their a preference? Perhaps Motorola? Maybe HTC again? We want to hear from you.
Since Samsung has become the top vendor of Android smartphones, Google will continue to have Samsung develop its next-generation Nexus models, leveraging Samsung's innovation ability with regard to the Android platform, and its ability to control the supply of key components, said sources.
