The Wii U system update due next month is being touted as a large one by Nintendo, and here's one of the reasons why. As previously indicated, the update increases the speed of returning from a game to the Wii U menu, but this video shows just how significant that speed boost is.
Going by this video, it'll take almost two thirds less time - from around 23 seconds to just 9 - to exit out of a game and return to the Wii U menu following the update.
While we can't test the update for ourselves just yet, we can and did verify the 'before' video's accuracy with our own side-by-side comparison; our Wii U took the exact same time to exit out of New Super Mario Bros. U. So no, no one sneakily pressed any pause buttons.
