It does support HTML 5 though
Hey, guess how long until the Wii U launches in North America? A little over two weeks. Two weeks; it hadn’t even crossed my mind. I suppose, then, that now would be a pretty good time for Nintendo to go into a bit more detail about the Wii U’s web browser that many of us have been wondering about. Oh, wait, they just did? Yay!
According to the specifications that Nintendo has posted, the Wii U will be able to display web pages thanks to the NetFront NX browser engine and supports HTML 5, though it lacks any plug-in support — this, of course, means no Adobe Flash. The list also makes clear that users won’t be able to save images that they find, neither will they be able to upload any videos or pictures saved on the console. Honestly, I don’t see that as a negative thing, especially considering its rather remarkable HTML 5 performance test results.
