He made this prediction 12 months ago. (You'll notice in the first video he says Bush has 18 months left in office. As of this month, he has 6 months left.)

By definition, his prediction is already proven wrong.

I would imagine a ds is a nintendo DS console.
And with wi-fi abilty, he sent his response via said console.

the world's population is dying anyways have you seen all the natural disasters that are currently destroying the human race i highly doubt its anything paranormal but we'll watch to see where this goes

I predict that over the next 100 years about 6 billion will die!! that is almost everyone walking the planet at this present time

Mind you no one lives forever
