Well, firstly, few are going to trust CNN, of all things, as a source for information relating to the future of video gaming, as their ability to do the news properly is rather debatable to begin with, and that's supposedly their forte!
I largely agree with RD's perspective: It's way too early to tell if motion controls are going to have a lasting impact. It's getting publicity at the moment because it's allowing a different audience a certain kind of accessibility to video games that they may not have had before. Whether or not it sticks will likely depend on whether that audience continues to find motion-controlled games as a source of reliable entertainment.
Personally, I'm of the opinion that it won't completely redefine gaming, but rather launch a new, more refined genre or style, as the technology develops. Motion-controls, as they are now, are just an alternate means of input, like the analog stick is an alternative to the D-Pad. As players become more familiar with motion-control schemes, it's likely going to become integrated into mainstream gameplay, and will become an option that players may or may not choose to experience. I wouldn't be terribly surprised if we get future copies of Madden NFL that allow players to choose to make a pass by using the Wiimote, or some other peripheral, to track a person's arm motion, or traditionally by mashing the analog stick and the X button.
As for saturating the market with gimmicks, I'm not worried. We've got a long way to go before we hit a repeat of the 80's crash. It's cliché, but all one needs for a reminder of those times is a copy of Atari ET. I'll take a motion-controlled Bejeweled clone over that tripe any day.
@ FaFniR:
Do you have an article to site, by any chance? I'm curious to see how far along that DS concept is, or if it's still just fudge spewing out of the rumor mill.
Found one.
If 256 by 192 lines of resolution make you squint to sort fingers from hands or eyes from eyebrows in 3D games, imagine a version of the Nintendo DS with twice or more per screen.
No one's talking tech specs yet, but in an interview with Japanese news portal Asahi.com, Nintendo president Satoru Iwata says a new DS is in the works that'll boost the handheld's visual verticals and horizontals appreciably.
According to Asahi, Iwata confirmed the DS is being developed in-house and will include both a high-definition video display as well as a motion sensor. Yep, a motion sensor. While accelerometer tech hasn't worked out so well for Sony's PS3 (the SIXAXIS gamepad, that is) it's pretty popular with Apple's iPhone, and I'm talking everything from games like Super Monkey Ball to "tilt" scrolling to carpentry tools.
Available when? Iwata understandably wouldn't comment, instead noting that the DS is experiencing record sales in the US.
Translation: Not soon.
