It'll overtake Halo's sales easily by May 9, 2008 tops (2 months after launch).
1st week? If the 1 million preorders were a couple months ago, then EASILY 2 million first week (if they were only NA). 4 million by the end of the month (which will only have 3 weeks remaining upon release).
Could I trouble you for some maple syrup to go with the plate of roffles you just served up?
