What is it about the Wii U hardware that you want people to pay attention to the most? Akagi-san would you start us off?
Speaking from the standpoint of casing design, while the basic structure resembles the Wii, there are various differences that made things more convenient. For one thing, the SYNC Button19 is on the outside. We heard that a lot of customers had made inquiries about how to synchronize the Wii Remote, so I thought there was a merit to that. Also, the USB connectors, which are only on the backside of Wii, are in front as well, making it easier to connect USB peripherals from the front.
