So total software sales in the UK were around 3 million the week Call of Duty World at War launched. Can we use this to narrow down the range for the first week sales of Call of Duty? Charttrack reported Call of Duty, World of Warcraft and Guitar Hero World Tour accounted for 25% of total sales in that week, so about 760k in total. So if we can estimate the amounts for World of Warcraft and Guitar Hero we know how many copies Call of Duty sold.
