I expect the 360 to drop to around 140-160k next week
PS3 250-280K
Wii 320-360K
the ps3 will drop slowest due to the fact its finally afforable for the average consumer to look into. 360 will drop the most because its been $199 for more than a year, and thats an issue for sales. PSP should stay ahead of the 360 for a while.
