I understand that the lack of social life have left you without a relationship or any friends and because of that you must be really lonely but I'm sure that your family must at least care. I wouldn't doubt that they're probably worried about your state of mind and how you have spent most of your life trolling on the Internet. This must be why you're so afraid to step a foot outside. But I'm here to help you through the process and with that being said, let go of the keyboard.... Let go of the mouse... And go outside to get some air! I promise that the sun won't hurt ya. If not for a stranger that's worried, please do it for your family that cares.
I recommend you go to your psychiatrist and talk this through. You should explain to him about the way you're spending too much time on the Internet, starving for attention and how you don't have any friends due to your zero existence of life. Do this quick before you completely lose your mind.
If the PS4 ends up being a big hit and people stop buying PS3 games, you can expect the PS3 and it's games to cut down immensely within 5 to 7 months after the release of the PS4.
Why don't you ask yourself that question?... You're the one making assumptions. Just because the PS4 cost less it doesn't mean it's for the unemployed. If you knew a thing or two about marketing, you would know that this is what companies usually do to promote their products. It gives them the upper hand against their competition and more consumers will be willing to buy.
