This is a question only a true fanboy could answer right now. We know little, to nothing about them Even there existance is mostly speculation, and guesses. I've been gaming since the NES days, and I know exactly what I want from a game console.
I've no idea which I'll buy, because I know nothing about them. (I know I'm only buying one this time around.) Hold on to your cash right now, see what happens in the coming months. If they're being released any time in the next 12 months we'll see them at the next e3, But no one knows anything about the systems, what games they'll have, I doubt even Microsoft and Sony know fully what we'll be getting from them yet.
Worry about this when they're due for release, and even then I wouldn't recommend you buy one right away. I would give it another 18 months after release, when they're cheaper, the problems have been ironed out, and they actually have games worth buying.
I heard 720 is coming out a year or two before the ps4. I think I would get 720 just because I don't want to wait that long. I actually think ps4 would be better though.
Ps I also own a ps3 and they're awesome.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
