Sorry Nintendo. That is the WORST controller I have ever seen for a couple of reasons.
1. Price. That 6 inch touch screen won't come cheap. I reckon that's going to go for £50+
2. Size. Its a big-ass rectangle. Its about as ergonomic as a giant NES controller.
3. Layout. Sorry Nintendo that control layout is just gonna kill it. Due to the large size everything's spread out and will just cause a load of trouble for playing any serious games.
Here's my advice to Nintendo: Keep this one for the casual market, maybe it'll sell well. Personally I don't think so but whatever. Make a redesigned, lighter, smaller, more ergonomic and above-all cheaper version for proper gamers. If I'm Playing Zelda I don't want a giant inventory screen between my hands, I just want a small one, around the size of a DSi XL screen. Everything shrinks down to a more manageable size for anybody without giant hands and we can play it well. Everybody wins
