As I've stated many times before, I don't OWN a PS3. Never considered purchasing one. I have a PSP with 5-6 UMD games and an Xbox 360 (which, to be honest, I haven't been using that much)
The ONLY game that would make me consider getting a PS3 is Uncharted 3 (never cared for the first two, but better late than never?) and Final Fantasy Versus XIII. If Versus XIII gets a 360 release, then I won't have to get a PS3!
Honestly though.. I'm cautious of the PS3 BECAUSE OF THE HACKERS. Microsoft has a set Code of Conduct in place against hackers and cheaters. Games are much more enjoyable because people don't have that freedom to do WHATEVER THEY WANT.
Sony's buckled under peer pressure by the hacker community because Other OS/Linux was removed and they were striking back against hackers abusing the console. Hell, the PSP has also had vicious exploits causing CFW, etc.. Let's hope the NGP/PSP2 has STRICT settings in place so hackers don't fuck with it..
