I just got impounded at the citadel after helping blow up that facility.  About how many hours do i have until i beat the main story line?  I'm playing on the normal difficulty btw.  I am having a ton of fun but i really wanna get my hands on ME2.
 
Oh, and another spoiler...this game is hella good.

not many. about 2 hours.
