I think it will be better if u give some PS3 estimates for Jan - June 2010 than fighting over how many weeks it will dip below 25,291... :D come on these 1 week sales doesnt matter to many rather its how much Sony is going to sell in a Quarter or in a Half yr.. SO the first Six months sales for PS3 in the previous yrs is:
Yr --- Sales
2007 ----- 515k
2008 ----- 560k
2009 ----- 580k
2010 ----- ??????
So make ur prediction how much it will seel in 2010... if it sells above 30k on average than in 26 weeks it should sell 30k X 26 + 100k for various game booasts... which is around 880k.. So who is saying it is going to sell above 900k or even 800k in first half of 2010 n who believes it will sell lesser than 800k in first six months..
Make a bet n settle this issue for next six months. :P
