Well, it's just what you read. If you have a Google phone Nexus S or a Motorola Xoom tablet, you should know that, at least for now, the company's intentions regarding these devices do not involve developing Jelly Bean for them. That is to say, that the Android 4.1.2 version could be the end of the road in which the advancement of the operating system is concerned.
At least, this is what you have indicated Jean-Baptiste M. "JBQ" Queru, Google's lead technician for Android Open Source projects (open source). That is to say, that something must know about what he says. If you want to confirm what he has indicated, you should not resort to an external publication, in this link from Google Groups you can find that it indicates that “there will be no 4.2 support for Nexus S and Xoom. Both models will continue to use 4.1.2”. Clearer, water.
So if yesterday it was confirmed While Nexus 7 and Galaxy Nexus were already beginning to receive Android 4.2, today what is known is that these models will not have the new version of Jelly Bean. Especially "bleeding" is what happens with Motorola Xoom, which includes an Nvidia Tegra 2 SoC and that, initially, it should offer enough capacity to receive its corresponding update.
The hope is external developers
It is what remains. If you have some of these models, surely you MOD developers, sooner or later, will make it possible to install Android 4.2 on one of these two devices. It is true that their creations are not official, but on many occasions the stability of their products is as good as the native one from Google and, in addition, they usually include really interesting options. Moreover, in this case, there is no other option.
If Google's policy continues in this way, it is possible that in the next update of your operating system one of your previous models will be "out of the game". Will it be Galaxy Nexus? Everything indicates that, perhaps, yes. we hope that what happened with Nexus S and Motorola Xoom is only a specific case and the lifetime of the Mountain View reference products is as long as possible.
