Although a long and tedious press meeting Sony had nothing of interest to me (or presumably my audience). They showed a lot of 3D (please put your glasses on, take them off for the next bit, put them on again, repeat endlessly) even though they only have one 3D capable camera (and you need two to get stereoscopy).
Everything has been previously announced but still, it’s important to waste the time of a couple of hundred journalists during their busy NAB schedule to just talk about what their customers are doing.
