Will PS3 and 360 continue to compete with Wii U for atleast two years more?

Now based on the site: http://www.computerandvideogames.com/342452/wii-u-graphics-less-powerful-than-ps3-xbox-360-developers/, it's very much certain that the PS3 and 360 will continue to compete. I guess Nintendo screwed up big time for 8th gen.
