Ok, here's a question: When (specifically which week) did the PS3 first outsell the 360 on a worldwide basis? Wasn't it in November or December of 07 at some point? Point is this: Go to that date and compare sales to date of both consoles (in total) and then divide by the number of weeks.
The last I checked (after MGS4 data were in), The PS3 was outselling the 360 by about 50K/week, on average, worldwide. Take the total spread and divide by 50K and you get the number of weeks remaining. The one big assumption is how big that spread will be over the holidays. Will it be 2X the weekly average? 3X? 4X? Even at 4X the average, we are talking 200K/week (!) times 8 weeks for Nov/Dec which cuts the lead by 1.6 million WW over the holidays. Figure that still leaves us with a delta of 3.8 million (5.4 million (today's number) minus 1.6 million this holiday). Divide 3.8M/50K and you get 76 weeks or about a year and a half. That would mean holidays 2K9 assuming the 4X multiplier pans out THIS holiday.
