Then: Nintendo explores alternative products with the heartbeat-sensing Vitality Sensor.
Now: After recently announcing a partnership with the American Heart Association, Nintendo appears to be riding the "Wii is good for your health" angle hard. We'd be shocked if some of the company's E3 2010 focus doesn't revolve around the initiative and we'll most likely see the return of the infamous Vitality Sensor.
Then: Microsoft unveils Project Natal, a motion-sensing camera system that lets players use their entire bodies to control games.
Now: Still shrouded in secrecy, Natal doesn't even have an official name as yet; nor have any games been announced for the platform. That said, we're expecting the remaining details on Natal to be disclosed at E3 2010.
Then: Nintedo debuts Wii MotionPlus, a physical Wii remote add-on that improves accuracy and control.
Now: With a severe lack of titles that take full advantage of Wii MotionPlus, the technology's implementation has been somewhat of a letdown. The only title to really shine with the attachment has been Wii Sports Resort, the very title Nintendo used to debut the product.
Then: Microsoft unviels Halo 3: ODST; teases Halo: Reach.
Now: After enjoying the success of the latest title in the Halo saga, Microsoft and Bungie recently released a beta for Halo: Reach. We'll be sure to find out more about Reach at E3 2010, including a definitive launch date for the game.
Now: PlayStation Move, as it has been officially named, seems to be a combination of Wii MotionPlus and
Project Natal, as it offers a more accurate sense of control and uses a camera to operate. We've had a hands-on with Move but will learn a whole lot more about it at E3 2010.
Then: Xbox 360 dashboard gets integration of Facebook and Twitter
Now: While these updates to the Xbox 360 dashboard were eventually implemented, their overall presence has
flown under the radar. Both services work, but they're hindered by the difficulties of text input and the
lack of a full-fledged Web browser.
