E3 has come and gone, but this year it has left us with the knowledge that some truly revolutionary products are coming in our immediate future. At least, Microsoft and Sony said they were revolutionary. There's been some disagreement over that fact.
The Kinect is a seriously impressive piece of technology. It isn't quite as accurate and smooth as the keynote demos showed, but you couldn't tell it playing Dance Central or Kinect Adventures. Sadly, Harmonix's offering was the only impressive one. Most of the other launch titles will be fairly bog-standard retreads of Wii titles.
The same is unfortunately true with the PlayStation Move. It is also substantially less intuitive (Sony's demo guys were quick to say that the Move took awhile to get used to) than either the Wii or (obviously) the Kinect. Also, there's no way that thing is going to stay with a real-life child for any length of time without ending up in two pieces.
Don't fret too much. The way Microsoft and Sony hyped their new controllers, it would have been impossible for the reality to not be a letdown. Hell, Sony's gigantic banners at E3 even had the words "THIS CHANGES EVERYTHING" emblazoned on them.
The sad truth is, hardware can only change so much. The fact that nothing truly jaw-dropping has been done yet with the Kinect or the Move doesn't mean either device is a failure. We've had the technology revolution, and now we need one for the content. Whether that comes from Sony, Microsoft or (again) Nintendo remains to be seen.
I'd hold off on a purchase until that happens, unless you don't mind waiting awhile for something cooler than Dance Central.
