E3 07: Nintendo press conference   Hardcore Nintendo fans
certainly weren't the focus of this year's press conference.
True, we saw the Wii Zapper revealed and finally got
confirmation on Mario Kart Wii (due Q1 next year) and Super
Mario Galaxy's release date (November 12), but the real focus
was the company's continued audience expansion. In addition to
showing Brain Age 2 and a new visual acuity game called Flash
Focus, Nintendo unveiled its secret weapon for its next casual
carpet bomb - Wii Fit, an exercise program that uses a wireless
mat.  Called the Wii Balance Board, the device measures weight,
body mass indices and balance. It's allegedly so fine tuned that
it can detect shifts in weight and feet, enabling you to
actually control games with your entire body. The demo reel
showed a hula minigame where you continually swirl while
extending your hands to catch more incoming hula hoops, and
another that's essentially step aerobics with Mii graphics.
There are 40 activities in all, including yoga exercise
