The 8 year figure im refering to for the PS2 relates entirely to Tyagis 2015 prediction. I dont expect the PS2 to be selling strongly in 2014-15 and never said as much either.
The PS2 sold 8 million units last year. Comparing this years sale to last its dropped by something like 12.5% so far. Even if it drops to 25% a year starting tommorow, it wont be far off 30 million by the end of 2015. If it has another year like 2007, it can drop a lot more than 25% each following year and STILL be in the region of 30 million in 2015.
Mr Tyagi, you seem reluctant but I would like to take up a "bet" with you...Can you put something along the lines of "the PS2 & 3 will not sell more than 40m combined between 1st Jan 2008- 31st december 2015" in your signature. Feel free to break that down into the 10m & 30m you stated for the respective consoles if you want!
