At Midnight on March 5, Nintendo officially released a download that updates the system to 2.1.3 U for all Wii U Consoles. Even though Nintendo released this small update, there isn't any noticable changes. Many people believe that the update could've been the fall update that was spoken about in the January Nintendo Direct Presentation, but it was confirmed to be an entirely different update than the upcoming 2 major updates for the system coming later this year.
Once Nintendo releases the Fall and Summer updates, the system is expected to be much faster than the version it launched with. It's very possibly that Nintendo could've just chosen a bad OS design and had to re-design a new OS from scratch. What would you do if you woke up one morning, got a new system update, downloaded it and once you restarted your system, everything looked different? It's highly unlikely that Nintendo would actually do something like this, but it's always a possibility when it comes to making a faster OS.
The Wii U has sold a little over 3,000,000 units worldwide in less than 4 months after launch. Nintendo hopes to sell 5,500,000 Wii U units by the end of 2013. If Nintendo can release a decent blockbuster of games by Fall, the Wii U has a high potential of selling much more than 5.5 Million. With the release of The Legend of Zelda: The Wind Waker HD this Fall, Wii U sales will pick up dramatically.
The first year of launch looks like it'll be the most difficult year for the Console. The same thing happened with their 3DS hendheld. Gamers don't have a wide game selection and starting this month, games are finally starting to hit retail shelves. Let's hope the next 2 updates can show how much potential the Wii U has in the 8th generation of consoles.
