This week Wii had 62% and PS3 20%

The week of the 16th Wii had 50% and PS3 had 28% 

The week of the 9th Wii had 51% and PS3 had 28% 

The week of the 2nd Wii had 54% and PS3 had 26%

The week of the 25th Wii had 52%  and PS3 had 27% (april)

The week of the 18th Wii had 60% and PS3 had 23% 

The week of the 11th Wii had 54% and PS3 had 26%

The week of the 4th Wii had 55% and PS3 had 26%

Fron those percentages I think it will be Wii as PS3 sits at 22% and Wii at 45% now, and because PS3 is more susceptible to shifts with xbox360 around the holidays.

 Or maybe PS3 will get there first only to be then back to below 25% as I dont think that by the time  Wii reaches 50% PS3 will have gotten to the same numbers as xbox360...

it will be wii that will reach it first

Wii is 4.4% away, PS3 is 2.8% away. Still the Wii gains more market share % each week, now even more because HD's are selling pretty bad in America and Japan.

Wii will reach 50% before PS3 reaches 25%.

Simple, the Wii.

In order for the PS3 to gain market share it has to outsell the 360 virtually every week, which it's now doing.. 'slowly', the Wii kills the combined HD consoles very easily resulting in always achieving it's increase in share.
