Okay, so first of all yes they are very small screens. And secondly yes you can't see much but these seem to be some of the first shots of a game running on the Wii.
Nice, crisp cel-shaded graphics and some nice lighting in one of the screens but probably best to think of this as just whetting the appetite for E3 starting.
And interesting note, they are still calling it the Revolution in one scan, looks like we're not losing that codename just yet.
One Piece: Ultimate Adventure is an upcoming title for Nintendo's next home console that features the popular anime/manga series, One Piece. Monkey D. Luffy, who gained powers whilst eating fruit, and his crew look out for the ultimate treasure known as "One Piece".
Stick with C3 for future updates.
