It's not a red herring in the way you put it hsrob. What Nintendo have done and are about to do is genius. They've finally perfected their motion controller and now the competition are trying to catch up but think about it, people don't buy the Wii because of the motion control. They buy the system to play the games. What Nintendo are doing with the Vitality Sensor is taking the focus off of their own now perfected motion controls just as the competition tries to jump into the action.
It's classic New-Nintendo. They're once again going for that blue ocean, they're trying to get consumers thinking about new software, they're trying to put themselves out in front saying 'look ok, now you can get motion controlled games on the other platforms and that's fine, but you can't get our own software and you can't get new experience like this one!' *points to the new Wii Lifestyle game that comes with the Vitality Sensor*
Simply put, Wii has all the strong mainstream franchises in the casual space and now will have a near perfect motion controller a year before anyone else. That means Wii is solidified in that position. Next year Nintendo will then take the focus off that and onto new experiences. It's not about the hardware but the software. They know what they're doing and I'm sure Microsoft and Sony have no clue.
Also Rol is Austrian not Australian, we're not crazy like he is :P
