Yes they are
Yes, the Dualshock 3 will work on any of the PlayStation 3 devices.
I have a Nyko iType2 PlayStation 2/3 compatible dualshock controller, that has both the port for the PlayStation consoles and a USB connector for your computer.
Amazon has a number for $5 to $10 instead of the $20 retail cost of the PlayStation 2 Dualshock Controller Black, although wireless models run $20
Maybe you do not have a Dualshock 3 with the Playstation emblem that you press to turn on the PS3 and controller
The Sixaxis Wireless Controller (SCPH-98040/CECHZC1) (trademarked "SIXAXIS") was the official gamepad for the Sony PlayStation 3 from launch until 2008 when it was succeeded by the DualShock 3.
While they can be connected they are always making you play with a handicap because they are not as good as the Dualshock 3 so why would you want to
No, it will be played with the standard Dualshock controller. The reason you may be confused is that it will have new mini games that will have move capabilities.
Yes it should be. Dualshock works on the PS3.
Nothing Major. Other than six axis and the fact it is wireless.

It depends. the only playstation 3 that i know of that can play psOne and ps2 games is the 60gb. The 60gb playstation 3 is the playstation that has the most features. It came with 4 USB slots, 4 memory card readers (located in the black overhang that is left of the disk drive), one sixaxis controller (not dualshock.. they are not as heavy because they don't have a vibrating motor so they don't vibrate), and the ability to read playstation 2 disks. i have not tried a psOne game, but i am pretty sure that it is capable of it. my friend has an 80gb playstation 3 and his cannot play the older playstation games. if you do have a 60gb ps3, then it will not play them unless you download something from the playstation store. you have to download "ps2 system data" or something like that. i have also tried downloading the system software on my friends 80gb and it still said that the ps2 disk was an unsupported disk. so all i know is that the old 60gb does and the old 80gb doesnt.
No, you can use the Sixaxis Wireless Controller, the DualShock 3 Wireless Controller as well as the PlayStation Move motion controller and navigation controller to play Killzone 3.
