PS4 or what's in the crystal ball ...
Oh my gosh, it looks like people have again more than enough time to speculate about things to come - in this case the next generation Playstation a.k.a. PS4.
Yes, someone at Sony is for sure working on that matter and I am sure it will be another fine product when it finally shows up on the market, but believe me, we are not seeing a PS4 before 2013, rather 2014. Sony actually wants to make good money with its PS3, which is still a big challenge for them ...
So, play those fine games to come and enjoy the power of the PS3 which is still hasn't been fully unleashed so far ...
