Sorry to tell you this, but 1) they aren't in pre-alpha and 2) you aren't going to see the game in 2008. I don't doubt there's a Resistance 2 being made, I just doubt the validity of this article.
If they were in pre-alpha, the game would be about 6 months away, possibly even less, and there would me more information out there.
Also, they aren't going to make this game in less than a year. If they did, I would be seriously worried about the quality of the game and worried that it would be pretty much just an expansion pack from the first game.
-edit-
I guess if you wanted to be a literal jerk, you could say that they are in pre-alpha since any game that hasn't hit alpha is pre-alpha but whatever. I'm taking the article as meaning they're about to hit alpha and that's just silly.
