I say Sony because it was Sony that took Nikon's marketshare. Why I don't think it it's big news to ordinary people is that it is not a huge difference for them. If I put a mirrorless camera in front of most people they would think it was an SLR. If you dig a little deeper you may find it even fits your old lenses with an adapter. It is hard for ordinary people to see it as even an important development. A digital camera does not require a mirror, so they made one without it. Without the mirror it is possible to improve on certain things in a small way. The camera business is a nerd business. Even small changes are good for sales. Ordinary people don't care. I suspect Nikon are being coy about this because they still have inventory of SLR cameras and lenses.
