Nintendo is providing tons of content for their All-Access Presentation @ E3 2012, which will be available in some form on http://e3.nintendo.com, Spike TV and MTV2, YouTube, Twitter, and Facebook.
The company's E3 press conference, which was confirmed a few weeks back, will be at 9 a.m. PDT on June 5. Later that night at 11:30 p.m. PDT, users will be able to view a Developer Discussion with Wii U Hardware Producer Katsuya Eguchi.
In addition, there will be a Software Showcase at the Los Angeles Convention Center on June 6 at 6 p.m. PDT. It appears to be similar to their usual developer roundtables that they traditionally have at every E3.
You can check the press release below to look at the myriad of ways you can follow along with Nintendo's coverage.
Nintendo World Report will be present at the press conference and the Software Showcase to bring you all the latest news and announcements.
