The one advantage that consoles have against PCs is this:

If I have a console, I know that any game or app that was produced for the console will work on that console. I don't have to worry about anything but storage, and I just upgraded my PS4 to a 6TB hard drive and the XBox One is even easier to expand. All you have to do is plug in a USB hard drive.

I think that aspect of consoles will keep them viable for some time to come. Just a thought.
