With all the excitement of Nexus availability and the Android 4.2 source code being pushed into AOSP this morning, one little statement by Android developer JBQ regarding 4.2 device support in the AOSP announcement was easy to overlook.
-There is no support for 4.2 on Nexus S and Xoom. Those devices should continue using 4.1.2.
Yep, that (very, very likely - it's intentionally vague) means exactly what you think it does: it's the end of the road for software updates on the Nexus S and Motorola XOOM (and yes, that means all variants). At least, that's what's implied. When asked for comment, JBQ said no further information could be given about future updates for the Nexus S or XOOM, which is the standard response to such inquiries.
