To people saying it's not a "monopoly", because of PC and Nintendo:
1) Triple A gaming on PC is not a thing for the vast majority of population. PC has never had the branding and media attention that the consoles have had. That the very possibility is foreign to most people, is a vast hurdle among with the price and the accessibility issues. ( Yes I'm well aware, building a PC, or especially buying prebuilt is simple, but its not something the vast majority of people are capable or wanting to do.) We, core gamers will always be the minority, and a small demographic when discussing as big of an industry as gaming has become.
2) Nintendo consoles have, and for the forseeable future will continue to have a vastly different demographic. The consoles have been carried by 1st party titles, excluding the massive explosion of the Wiimote titles in the last generation. (Something that the WiiU isn't even close to matching) It just currently seems unlikely that the 3rd party franchises that make up the backbone of the industry (GTA, Call of duty, Battlefield, Fifa, Madden, Need for speed, Forza, Gran turismo, Assasin's creed, to name a few) would suddenly find themselves successfully ported onto the WiiU, especially since unlike the Wii the install base is smaller than the PS4.
