During the January Nintendo Direct, it was announced that two major updates were planned for Wii U. The first arrived on schedule, having launched in April. The second – scheduled for summer – may see a slight delay.
A note on Nintendo’s Wii U update page confirms that the next major update will be available between the end of September and beginning of October. It will bring about “further additions to system functionality”. Among the changes should be even faster load times.
There you have it. We can definitely rule out an imminent arrival for the big firmware update. With summer ending on September 21, it’s also possible that Nintendo could miss its originally intended release window.
