It appears that Samsung and Google have decided not to launch the Galaxy Nexus (or Nexus Prime, or whatever it's called) and Ice Cream Sandwich at their October 11th Unpacked event. The two companies sent out a joint announcement reading:
Samsung and Google decide to postpone the new product announcement at CTIA Fall. We agree that it is just not the right time to announce a new product. New date and venue will be shortly announced.
The press event on the 11th was expected to be not only the debut for the successor to the Nexus S, but our first good look at the next version of Android. For whatever reason the companies have decided to delay that launch. But, if Eric Schmidt is true to his word, we shouldn't have to wait too much longer... he did promise us that it would launch by November.
