This analyst micheal patchter right before the systems ps3, and the wii released, he said that a $249.99 wii was going to outsell the 360 and ps3 for the first year. Simply because its a cheap nintendo console. He also said it would sell very well. He also stated sony would look like the clear "looser" Because of the price on the console which would hurt sales for its first year....(wtf is he psyhcic?)
Also the analyst said that if blu-ray would be able to obtain the dvd market the ps3 would be the clear winner in the long term.
Now all that he states in this video, recorded in 2006 has happened. Also I predict as a sales guy myself that after Q1 2008 wii sales will drop to around 100k world wide weelky. And ps3 sales would rise to around 200k sales.
