how much are those controllers going to cost

I break mine a lot
Probably the same as they always have been.
Also LT, Ive heard they're changing their controllers. No more dual shock. It will be something similar to wii's. Except you can put them together not by a cord. Both halves have Move.
Nah, that was a patent they filed. The latest leaks are saying that it's going to be a controller just about the same size as the current dualshock 3 except with a little touch pad and a "share" button.
And I agree, the price will probably remain about the same. I wounldn't be surprised if the current Dualshock 3 will also be compatible with PS4.
