i have 2 question about ds3

does it have same battery charging like sixaxis

and u know how much it cost

yeah it charges same way... but the rumble should use the battery twice as fast...

and you can import them for about $70 already...

1) Yes

2) Not really sure if it will be more than the sixaxis or the sixaxis price will be lowered to make room for the Dualshock 3
