Well the new Sony Console the "PS3" was Sony's biggest failure, at the launch alot of units were sold, beacause, they thought it wil be better than Sony's accomplishment, the PS2. But peaple were killed for the PS3.
In christmas 06, the most wanted christams item was the PS3, and Wii tied.
In 07, the high sales stopped. And then peaple went for the other systems, why:
The reason why the console was $600 beacause of the Blu-Ray, thats also how the games cost from $50-$100.
What it stole from Wii and 360:
Well, even though the Wii released later than PS3, PS3 copied Wii, Motion Scencing, that 1 2 3 4 thing on the controller.
Also PS3 copied 360s guide button.
