Yuoaman, that better be sarcasm in your first line. No one here is an expert.
Bianca, I do see that you are cynical, but you don't exactly know whether this is another minor update akin to the DSi or if it is an entirely new console. If I were you, I wouldn't persue that argument any further. There's no information backing up any side of that argument, so you are basically fighting over speculation (which gets you nowhere). I do agree that Nintendo is taking a bigger risk with this, though, mainly because I do not know how they are going to pull it off. I can kind of see where you are going with the motion sensing argument, but to be honest, the reason why it's a big success for Nintendo is because they made it a fluid and intuitive input method for non-gamers and casual gamers. The Eyetoy did try, I'll give you that, but at the time, Sony didn't take into account the technology limitations (One of my favorite things was not being able to use my Eyetoy in my basement because of "ineffective lighting"). In addition, Sony didn't market it effectively, nor did it really put much thought into the peripheral after launch. But about Nintendo being sloppy, not really. If you break down there systems hardware wise, you would see that. Nintendo used an updated version of the Gekko CPU for the Wii for a reason: it was cheap. Same goes for the GPU. The Wii itself is also really easy to assemble, requiring less time in the factory and less being spent on production. The Wii was a carefully calculated risk, to ensure they made money on the console, no matter how the market turned on them. That isn't sloppy.
Jolene, I can see where you are coming from too, but the Wii and the DS were big risks. While not neccessarily to Nintendo's coffers at the time, down the road they could have been. Let's take this back to the third-pillar thing. Back when the DS was announced, they had said that they were going to introduce the DS as the third pillar to there lineup. That, right there, is caution. At the time, the Gameboy name was a household name. So if the DS didn't catch on with the masses, they could just anounce another Gameboy. The DS could just be swept under the rug, just like the Virtual Boy. And as I said before, the Wii was a carefully calculated risk. All the internals, and the console itself, really, are made to produce a profit, no matter what.
