It's too early to be thinking about it.

they've already rumored a playstation 7 in one of offical ps2 mags a while back lol

First of all, Sony is most definitely working on the PS4, even if it's just the planning stages. Nintendo is working on the Wii's successor, and MS is working on their next Xbox. All three console makers have, in one way or another, already confirmed the existence of their next console.

That doesn't mean you should expect it anytime soon though. Console development often starts much earlier than you'd think. In fact, Nintendo has already stated they were working on the Wii's successor (planning phase) before the Wii was even released.

It takes a long time to get everything together for the console, it's not just a decision to put some hardware together, mass produce it and sell it. It's a much more complex process than that. The companies have to watch the market to see what consumers want, and use that to determine what direction they want to go with their console - for example, Wii motion controls.

They also have decide what hardware to use, and build the development kits, which is probably one of the most time consuming aspects of developing a console. Then the console OS and it's features are pulled together, and it's released to third party developers so there can be games ready for release at launch, meaning 1-2 years after the console is generally ready, they still can't release it.

Basically, it's a long process, Sony is working on the PS4 without a doubt, but you won't see it for a very long time, at least 2012-2013.

i know there will be a ps4 but not untill at least 2012 the ps3 still has alot of life 2 it and the ps3 hasent even been out for 2 yrs come on now there is still alot of life left on it

We are years away from that although there is probably some very loose talk about the whats and ifs about a console all companys have 5 10 even 15 years and more plans. They have never stopped thinking about what the next one will be like. They haven't even scratched the surface on the things that they want to do with the PS3 yet I'd say we have at least another 5 years before they even start the development of a new console. As strong as the PS3 is can you honestly think of anything more that they can do with a home game system right now.

I've read stuff from websites about what they "think" will be in the Playstation 4 and stuff like that, but it's just speculation.

A Playstation 4 is still a very long way off.

Sony has introduced each of it's new systems in 6 year cycles, and a PS4 wont be out until 2012 or later.

NO, and why would u want one anyway? PS3 is good enough. if it isnt i'm sure either 360 or wii are.
