When is Sony PlayStation 5 coming out?

Is this the new PS5?

It's been 20 years since the first PlayStation was released, and there were seven years between the launches of the PS3 and PS4. With E3 2015 just around the corner, one question game lovers are looking forward to ask from Sony is: How long will we have to wait for the PS5?

Not only does the PS4 bring in a huge amount of profit, Sony boss Shuhei Yoshida has been quoted as saying the future of the PlayStation is up to developers. Indeed, if rumours are to be believed it's about to launch two new PS4 models in 2015, so it won't be turning its back on the platform any time soon.
