Nintendo has several smaller scale events planned with the focus on titles for the NA market this E3. That is, instead of their one, large presentation they typically hold. Iwata will not appear at any of these events. Besides that, they're investigating a new means of transmitting this information directly to fans that can't attend the event.

At E3 this year, we are not planning to launch new hardware, and our main activity at E3 will be to announce and have people experience our software. Many people are certainly very interested in learning more about the Wii U titles that we are going to announce. We will use E3 as an ideal opportunity to talk in detail mainly about the Wii U titles that we are going to launch this year, and we also plan to make it possible for visitors to try the games immediately. As a brand new challenge, we are working to establish a new presentation style for E3.
First, we decided not to host a large-scale presentation targeted at everyone in the international audience where we announce new information as we did in the past.
Instead, at the E3 show this year, we are planning to host a few smaller events that are specifically focused on our software lineup for the U.S. market. There will be one closed event for American distributors, and we will hold another closed hands-on experience event, for mainly the Western gaming media. Also, I did not speak at last years presentation, and I am not planning to speak at these events at the E3 show this year either. Apart from these exclusive events for visitors, we are continuing to investigate ways to deliver information about our games directly to our home audience around the time of E3. We will share more information about them once they have officially been decided.

まず、例年のような世界中の皆様に向けた全方位向けの、新しいニュースを発信するような大規模プレゼンテーションを行わないことにいたしました。
それに替わり、より小規模な米国向けソフトに焦点を当てた複数のイベントを計画しております。そのうちのひとつは米国流通関係者の皆様向けのクローズドなイベントで、もうひとつは、主に西洋のゲームメディアの皆様を対象としたクローズドな体験型のイベントです。また、私は昨年の「プレゼンテーション」に登壇しませんでしたが、今年もこれらのイベントに登壇する予定はしておりません。これらクローズドな来場者向けイベント以外に、E3の時期に当社からゲーム情報をご家庭におられるプレイヤーの皆様に直接お届けする新しい方法を継続して検討中ですので、決定次第、改めてお知らせしてまいります。
