When will see a Wii, PS3 and XBox360 slim models appear on the market?

[DirtyP2002]

There will be a slim model for the 360 in August09. They will sell it for  more than one year untill the next Xbox will be released in November 2010. By that date, the 360 would be 5 years old. MS will support it another year before they strictly focus on the Xbox3.

Wii won't get smaller, why should Big N do this?

PS3 needs to get smaller. This will be a big point for Japan. so i guess November 2009.
