While there are some factors (mostly game releases) which will predictably increase sales around there release (to some extent), the vast majority of mid-year console sales are driven by the unpredictable motivations of individuals; and while a fairly large (over 5%) sales increase or decrease in a timeframe of a quarter or longer may be meaningful, on a shorter term basis it is just random noise.
