Sony’s PlayStation 3 is backwards compatible with PlayStation 2 games, but not with PlayStation 2 controllers. So those upgrading to Sony’s Blu-ray Drive console will need to seek out additional controllers. And there are plenty of options out there for this console, including the earlier SIXAXIS controllers that offered motion-sensor controls and the new controllers with vibration built back into them (the result of a lawsuit settlement) and tilt-functionality.
When it comes to just how many controllers the PS3 can handle, there are many different hardware iterations (especially for such a new console). Sony’s 80GB, 60GB and 20GB PS3s have four USB ports for controllers. The streamlined 40GB PS3 only has two. But all versions support up to seven controllers, which only use the USB ports to charge the wireless controllers. The Bluetooth controllers connect wirelessly with the PS3.
