Attach rate varies wildy from one installment to the next and is an extraordinarily poor way to determine the sales for the next installment in a series. MGS4 having a far greater attach rate than MGS3 should have made this fact so painfully obvious but somehow it didn't. This example is relevant because is shows how attach rate is useless in making predictions.
