Update: Samsung has just updated their global blog to reflect the postponement of the event.
In a move that at first glance (and based on their short press release)seems related to the passing of Steve Jobs, Samsung and Google are postponing the launch of the Samsung Galaxy Nexus/Nexus Prime and Ice Cream Sandwich.
“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.”
