Yes, I do believe the story was described at E3 '06 as this:
"Survive nature's most devastating catastrophes in Disaster: Day of Crisis, a panic-inducing survival game for Wii. In a devastatingly short period of time, an unprecedented wave of natural disasters has pummeled the United States. On top of this inexplicable series of disasters, a rouge special forces unit has taken advantage of the chaos and seized a nuclear weapon. Only Ray, a former member of an elite rescue task force, has decided to take a stand."
So as far as I'm concerned, the story hasn't changed...and I actually seem to remember them mentioning "extensive voice work" back then as well.
Apparently this "new" news is already all over the internet though...weird.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
