this is the best thing I've read today. And it seems just about 100% accurate.
. . . I think what it is, is that people want something new that works. Obviously, the Wii remote was new, but it worked. Then, Sony and Microsoft finally realized that there's a different way to game, and they do some stuff. Meanwhile, graphics is whined about against the Wii, but hey, you have a product that doesn't look like a underdog rip-off, and sells well to boot. Graphics aren't the best, but they pioneered a certain technology with gaming and are running with it.
. . . Then, Nintendo tries something new, while stepping up to the graphics plate, per se. So we'll see, in a year or two, Sony and Microsoft will try to one-up Nintendo and the WiiU, probably with Sony trying to do a handheld controller w/screen, or hell, maybe a double screen, with one of them being a touch screen! Meanwhile, Microsoft will resort to a handheld controller that responds to hand gestures.
. . . Hell, I don't know. It seems that Nintendo has the right idea and Sony and Microsoft don't quite realize it, but they'll still try to do a one-up on graphics, and claim they're better because of it.
tl;dr Nintendo has the right idea, and Sony and Microsoft try to cover their asses when they realize their disadvantage.
