Without an appropriate time frame given all I can really say is "no." "For Good" would indicate that it never at any point stops selling, and there will be a point at some time in the future where any console will stop selling. Sorry, but I majored in History in college and vague timelines annoy me. It one of the reasons I am not really gonna way in to strongly on any "will x console beat y or z console debate." There are plenty of factors that haven't even become known to us yet and it is far to soon to draw any conclusions. There are known patterns in the industry, but it is important to note that as much as the past can be a guiding force and can help you make an educated guess- it is far from a crystal ball. The events that shaped one generation are not guaranteed to play out in the exact fashion again. All anyone can really do is put as much effort into an endeavor as possible and hope that either things work out or that history cuts them some slack.
