It's this idea of 'trending' that's down-right preposterous!
You don't 'trend' the London Marathon 3 minutes into the race. You don't 'trend' the Premiership after the first two matches. You don't 'trend' Wii's sales over the last two months. Hell, they're getting half the sales now as a month ago. That's a trend of half the demand every month! By the end of the year they'll be lucky to sell Wii's in the thousand if that trend continues! Trends means looking for patterns, which needs a relevant amount of source material. eg. If I show you a pattern of black white black white squares in a row, you may 'trend' that the pattern will continue like that indefinitely, whereas it might be anything far more complex.
You're opinions on Sony's loss of market share, low sales, etc, may well be right...BUT...you can't use the first few months of sales as evidence of that. Those numbers don't fit into any logical argument as they're statistically incomplete, given that the current 'trend' can be changed by a whole host of options by Sony (and not just cutting the price, which some seem to think is all you can do to sell more of a product).
Golden!
