wouldn't be too difficult m8.
You have all the software sales, just take the SW sold by the year and divide it by the number of consoles sold.
Then create a total
Then do the same for lifetime, including last 4 months of each year. Use the average attach rate that you got and subtract the average attach rate for the first year of sales. Soon you will be able to predict how many SW sales will occur any month of the year.
