When are all three going to be released, that will make a big difference as well.

Natal is late 2010, PS Wand/Gem is spring 2010, Wii Vitality Sensor ?????

I believe they said the vitality sensor was 2010, at least hinted at it. Maybe I should have said "in their first year", but I wanted to see if anyone thinks a late launching Natal could beat the Gem, or if the Gem will win by being first, etc.

If its in their first year, the Vitality Sensor will outsell both Natal and the Wand combined.  If it was just 2010,  it would still probably be the Vitality Sensor but the Wand could have a shot at it if it released late enough
