Nintendo Direct's been a pretty good way to inform the public on anything happening at Nintendo. E3's around the corner and that's usually the place that new games are playable and by a select group. The public could only watch, but that's going to change this year.
Reggie Fils-Aime announced at the end that they are partnering with over 100 Best Buy stores to allow the public to play select games there during E3. No specific games were announced, but it's a good bet that it would be many of the titles being shown at E3. This is a pretty nice move on Nintendo's part to grab some publicity and let a large population try out their upcoming games, not just those attending E3. I hope more companies start doing this.
