As for most of us, the day before the launch is the longest day.
So what are all of you out there doing?
I am at work until this afternoon, then on to play a little farewell Reach, then to a local Bestbuy to hopefully win the tournament being held 
Then
HALO 4
I myself am stuck at work also. Watching some MLG from the dallas event. Prolly goin to finish my Halo Reach Disc Destruction Montage. And then prolly idk…just super hyped for halo4 , havent been this hyped since halo2 release =D
Watching lots and lots of Hardcore Pawn to pass the time.
I may actually go into work today. I got up to level 5 of the campaign and so far the game is underwhelming.
School then heading to wait in line.
Getting EVERYTHING out of the way so Tuesday will be distraction free
extended farewell Reach session. i would expect to see the reach population to be much lower and only get lower as the day goes on…
Working; waiting for my Best Buy email to show up so I have something to do at midnight ; )
About to stock up on Doritos and Mountain Dew for the long wait in line tonight!
Sleeping 
Getting college out of the way. Then heading to Gamestop.
I still have to do the last two missions of Reach on Legendary solo. I stopped going for this achievement a long time ago and I have to do it today or I will never come back for it. Plus this is the first Halo since Halo 2 I haven’t done on Legendary. :S
after i college today i am going around 8:30ish to sign up for the tournament at Gamestop and play until i lose or win. and then paitently wait in line for my copy of the LE.
Browsing the Halo Waypoint forums when I should be revising for maths.
Waiting… just waiting.
In all seriousness, I have a lot of work I need to finish before tonight. I did my homework today already and I have a test tomorrow so Im studying before 8. After 8, its Halo prep time.
Coming home from school, getting something to eat, spend a few minutes on waypoint then going to a friends to pass the time.
Just waiting until I get home, trying to decide whether I should skip tomorrow or Wednesday. Hmm should I take a quiz tomorrow, or should I skip and take the quiz the day after…
Homework… Lots of homework… -_-
College classes, hanging with the wife and son, then going to GameStop with my bro to check in. The nice thing about living in a small university town is that we don’t have to camp outside of GameStop to get our games in a reasonable time. If we go there at 11:45, we will be home by 12:20.
I just finished college. Now I’m waiting to go to the Halo 4 midnight launch.
