Many of the Android blogs are reporting that the Nexus 7 has been discontinued. Although I haven't found an official notice from Google, the machine is no longer listed on Google
Of all the tablets I've owned, this one is still the best and is used daily. For me, seven inches is the perfect size. With a case, it still fits in a cargo pocket, which makes it easy to carry.
I predict this machine will be the "Windows XP" of tablets, in that it will be in use for a long, long time.
