I find it hard to believe that they arn't thinking about it already - where there is potential profit, there are firms desperate to be part of the gold rush.
Them not being publicly open about their research fields doesn't mean they aren't thinking about it, or aleady working on it behind the scenes. In most cases they wait for one major entity to step up and get itself involved in a specific new market, where the others then with great interest watch and learn from the mistakes and obstacles the first mover (Samsung in this case) faces. The negative point of such approach is that if Samsung does happen to do everything right from the start, they with their first mover advantage will be able to outplay other tech giants with great ease. Samsung has the capacity to deliver in large volumes, which directly allows them to offer a lower unit price than their closest competitors, so it's going to be more than interesting when it comes to how Samsung is going to demolish Jihan's empire slowly but surely. What Banks felt when Bitcoin popped up, that same feeling has Jihan when Samsung popped up in his market field.
