i dont think the original storyline was scrapped but more like on pause. theres no real reason to start over something thats been fleshed out and the basis of the whole game. it takes a long to flesh out a storyline and what we are getting now is prob a side-storyline of sorts, either that or its just a small piece of the main storyline.

the new team never said anything about throwing out the original missions but were more focused on the gameplay aspect. i dont doubt that once thats done, we will see a lot more of the storyline especially with expansions.
