Sony's Kaz Hirai answered a question about the PlayStation 4 showing up at this year's E3. "Andy (House) is absolutely right in that we are not making any announcements at E3. I've always said a 10-year life cycle for
ps3 released 16 may 16 may 2005. so summer 2015. still 3 year to go.
Last quarter 2013, SONY will release the new playstation 1/2 years later which ultimately again will have better hardware however everyone will already have rushed into buying the Xbox "720" and i'll have th xbox fanboys trying to convince me im wrong about what machine is better joy of joys ì_ì Would rather it never came out and we all moved back to loving the playstations like the good old days of PS2.
Wait for all of them to be released, play all of them, buy the best one and then talk.
ok, i belive that the 720 is just something that microsoft have been talking about behind closed doors. the it got leaked to the public and crazy fans have done this and that. Im not saying that their might be one coming out, its just fans of the xbox has used thier imagination. and made other people think that its alredy been dsigned and wating to be released.
