It was only a matter of time, but Nintendo has officially discontinued the Wii in Japan.
Even though it will still be on production in other parts of the world, the fact that Japan has decided to end it, it feels like a long and quiet goodbye for the console.
For the past seven years, the Nintendo Wii has entertained many gamers of all types, especially the newcomers. The Wii-remote, for better or worse, has changed the way games are played forever. Games such as Super Mario Galaxy, The Legend of Zelda: Twilight Princess, No More Heroes, and many others made the Wii as long lasting as it did.
Nintendo also, for the first time, introduced downloadable games from past systems (NES, Super NES, and Nintendo 64), even from past rivals (Sega, TurboGrafix-16, etc) through the Virtual Console. While did it feature many games (Super Mario Bros, Double Dragon, Castlevania, Ninja Gaiden, etc), some notable ones were left out (Yoshi's Island, Tecmo Super Bowl, Turtles in Time, etc.) and it not feature online multiplayer for those games.
WiiWare did make things interesting with Mega Man 9 and 10, Retro City Rampage, and Konami's Rebirth series, but just like the Wii's retail games, it was also plagued with many "shovelware" games that appealed to mostly casual users; and this is where the Wii's biggest weakness was.
While there is no debate that the Wii sold the most consoles with 100 million units sold, it seems that in retrospect, most of the audience was for the casual gamer: people who want simpler and cheaper games. This, in turn, turned off many "hardcore" gamers that are interested in bigger, triple A, blockbuster games
Unfortunately, with the iOS and other mobile devices, it will be very difficult, if not impossible, for Nintendo to capture that audience once more with the Wii U. With it's projection of 50 million lifetime units sold, Nintendo will have to work really hard to recapture the "hardcore" audience once more, now that the PS4 and Xbox One are slated for release next month.
