Well I've had around a week to play with this device and calling it awesome is a bit of a understatement. The rumble is super sensitive going from barely moving to full on vibrate out of your hand mode. Ratchet & Clank blends great with it, when you fire a weapon you get feedback, when you get hit you get feedback, however if the enemy is far away and and you get hit the feedback will be less than a enemy at point blank range. GT 5 Prologue Demo has excellent use of vibration functions and does a great job at really showing off the varying degrees of feedback that the controller can do. Uncharted, COD4, and pretty much nearly all the games in my collection work in some way with the vibration. Developers had to have known this was coming as its working on games that aren't even on the official "supports rumble" list on the Japanese PlayStation site. I love the weight that it adds to the controller, it feel "just right" now imho. Here are some photos. The last one with the TV display basically means if you can see that menu (PS button -> controller settings) then the game will support rumble in some fashion. I'm no expert in writing reviews, sorry if this is lacking information. Feel free to post any questions you have and I'll try to answer them. Overall a great controller, definitely need to pick yourself up one when you can. The price is 5,500 Yen which is around $46. I will assume that they will be $39.99 when they are released in the US. The release date for US/EU is Spring/Summer 2008.
