If it coninues like these(based on charts from april 5th) the ps3 will catch up in 63 weeks.

186 000/(11.6 *10^6)= 0.015(ps3)

134000/(18.1*10^6)=0.0075(360)

1.015^x*11.6*10^6=1.0075^x*18.1*10^6

(1.015^x)/(1.0075^x)=(18.1*10^6)/(11.6*10^6)

1.0079^x=1.56034

(log 1.56034)/(log 1.0079)=63-64 weeks


In europe 19 weeks:


100 000/5.2mill=.02(ps3)

66 000/6.2mill=.01(360)

5.1mil*1.02^x=6.2*1.01^x

1.02/1.01= 1.0099=1.01^x

6.2/5.1=1.21

log 1.21/log 1.01= 19 weeks

You're using a wrecking ball to hit a nail in a two by four... this is simple math

PS3 is outselling the 360 by 52,000 units/week so it will take 123 weeks for the PS3 to catch up to the 6.4 million consoles its behind... NOT 66

Wrong, you say that as if for those 123 weeks the 360 doesn't sell a single console. It needs much mroe than 123 weeks to catch it, saying it sells this constant, for both the PS3 and the 360.

No you fool, the difference from week to week between the two is roughly 52,000. Therefore if that difference continued it would take 123 weeks for it to fill the 6.4 million gap, if the 360 didnt sell a single console and the PS3 kept averaging about 170k a week it would only take 37 weeks.
