Its much more immersive, without giving any real advantage. The only real difference is you can easily turn your head to look around via an accessory like the TrackIR which is easier and faster than havin to turn your whole body which when moving also changes wehre you are movin too. Your view is no better than without it as far as givin any advantage like third person does. Gives no advantage other than you can run one way and look another, but that does mean you cant see where you are running. Not sure you understand what he's talkin about. Sounds a bit overpowered and sounds like it can even encourage some camping to how third person is now in PS. I do not know about the whole head turning and keeping your gun pointed in one area at the same time. This would be INCREDIBLY useful at nighttime when you would have to rely on spottitng muzzle flash or tracer fire to avoid getting swatted, I use it all the time in ARMA 2 and the number of times that being able to look around as allowed be to see the backblast from a Strela or Tunguska launch or an enemy AAA vehicle has saved my life is massive. With the ability to turn your head you can look around to see enemy targets, vapor trails from rockets and incoming tracer fire.

It's the same with many pilots, especially in the old days before people learnt the ropes, full galaxies would just fixate on their drop target and ignore aircraft off to the flanks because the centre of their vision was on the base roof. This is exactly what I mean about a 'head movement' feature, many aircraft get target fixation and tunnel vision, I've even been playing with friends and specifically tell them not to attack an enemy due to the volume of anti-air yet they do it anyway because they can't see the Triple-A in their tunnel field of vision so they instantly think that I must be seeing things as their target fixation makes them desperate to get a kill.
Perhaps a local voice chat would be too open for abuse to be implemented, it would be nice to have some form of directional voice chat though. The only reason I'm suggesting it is because some of the coolest moments in Arma 2 have been times when I've ninja'd enemies and got close enough to hear them giving each other orders during multiplayer or simply chatting. It would just be a proximity voice chat that would operate as if your ingame avatar was speaking out loud, the enemy team could hear it (Possibly, this could make door camps and bit 'chaotic' as I'm sure all you would be able to hear is attackers screaming "Leeeroooy" or "CAMPING N00BS" ). I know how resource/bandwidth hungry a local VOIP would be but it is still pretty cool. Even games like Bad Company 2 had horrible system resource utilization when they were released however they were console ports.

I'm sure multi-GPU setups and quad core processors will be supported by Planetside (And I am aware that crossfire/SLI support is more dependent on Nvidia/ATI putting effort in but Sony can press them to get the drivers out) but given how many games out there release without proper system compatibility you can never be too careful. Being able to look around in a jet massively improves situational awareness and it's incredibly useful in these vehicles (especially if 3rd person is getting the boot) It would be INSANELY useful in aircraft, it was in Battlefield 2 as you could spin your head around in the helo's to spot targets. Obviously this is quite a big feature to implement and I can't see it being worth the effort it takes unless the game is a milsim or realism game but it's a nice little feature.
It's extremely useful in a game as it allows you to survey and area while keeping your gun pointed in the place you are needing to cover, it also means you are talking to people you can turn your head to them rather than spin your whole body and point your gun in their face, it feels a lot more natural.
There is a feature that isn't present in many games - the ability to turn your head independently of your body or vehicle In OFP/ArmA/Arma2/OA you can hold down the LALT key and turn your head without turning your body, you can also use a system like natural point (TrackIR) to do this without keybindings. if your buddy is to your right and is giving orders the sounds actually come into your right ear) then it can become extremely easy to immerse yourself in a game. Using surround sound can really build a great gaming experience, having directional sounds allows you to pinpoint enemies with more accuracy, if you link it to a voice broadcast system (e.g. With immersion being one of the most important features of a game I think its important to add the little details that really increase the believability of a game.
