The confirmation of lack of support for DVDs and Blu-rays comes from the Nintendo President himself, Satoru Iwata, during an investor Q&A. During the Q&A, Iwata-san informed the investors the “Wii U does not have DVD or Blu-ray playback capabilities.” When asked what the reasoning behind the lack of support, Iwata-san said, “We feel that enough people already have devices that are capable of playing DVDs and Blu-ray, such that it didn’t warrant the cost involved to build that functionality into the Wii U console."
Iwata-san does make a good point. The Nintendo Wii U doesn't need to support DVD and Blu-ray discs, especially since the Wii already has support for the online streaming video service, Netflix. I personally have not popped in a DVD or Blu-ray into any of my consoles for years now as the majority of my movie watching has been done on Netflix. As long as the Nintendo Wii U will continue to support the service as the Nintendo Wii does, I'm sure all will be forgiven for those of you who still prefer to watch DVDs and Blu-rays. Although there's absolutely no help for the guys who still watch movies on Laserdisc, VHS or Beta.
