While the Wii U usually comes in either in a White Standard Bundle that comes with an 8GB hard drive or a Black Premium Bundle with a 32GB HDD, this new package will allow Japanese customers to mix the colour of the former with the larger storage space of the latter. While it's due out in the East on July 13, there's been no confirmation just yet if it'll be heading West.Additionally, the company also announced a new and improved battery pack for the Gamepad controller . While the standard 1500mAh version that's bundled with the console offers between three to five hours of life, the new 2550mAh capacity pack will increase this to between five and eight hours. Due out in Japan on July 25, it's set to cost ¥3,150 (around £20 / $30 / €25).While they're easily the most exciting announcements, Nintendo has also officially unveiled a Quick Charge Set for Wii Remotes. Seeing as third-party versions of these have been around for some time, chances are you'll have an equivalent, but if not you can pick up a battery pack, charging dock, WiiMote case and strap for ¥4,200 from July 13.Lastly, a new Nintendo Land bundle has been unveiled that'll offer you a blue or pink WiiMote Plus in addition to the game for ¥5,985.We've heard nothing about any of the above launching outside of Japan. We reached out to Nintendo but were told this is a Japanese release, but other territories will make announcements if relevant in due course.
