i'm not a business expert, but i am a mathematics expert, and it is highly ignorant to use a linear regression model to say anything at all about our present discussion. yes, the ps3 is selling just over 100k a week, but that does not mean you can treat that number as a mean. price cuts, game releases, and holidays all cause spikes in the numbers. the only meaningful way to talk about the numbers is to speak as generally as possible over the whole data set. the ps3 has clocked in about 10 million units sold a year. if we were to assume linearity 2009 would yield about half that. but that's not the case. if you really wanted to predict performance one would have to look at several key points in the year and draw a percentage. this could allow one to extrapolate the rest of the year.
