One of the current battlelines of the future of console gaming is whether or not people will buy dedicated gaming devices to play games on, in sufficient numbers that these platforms get their own exclusive content or not. As smart devices appear to be powerful enough, casual gamers could decide to back off buying a dedicated device, and you are seeing this happened. "Nintendo is doomed" comments are coming out of this trend. And I do believe Nintendo gets targeted with this, because portable gaming devices have been their bread and butter.
