A new rumor suggests that Sony is already planning for the PS5 as early as now.

Insiderp reported that the PS4-maker is in a "contractual agreement" with Micron for an alleged "ReRAM, aka next generation of blisteringly fast 3D stacked RAM variant." In comparison, "the PS4 uses 8GB GDDR5 as well as 256MB DDR3 RAM for background tasks," stated Gear Burn.

Japanese website Nikkei Technology said:

"The latest technology is targeted at SCMs. But it is unclear whether the technology is used for servers at data centers, smartphones or tablet computers. Sony said that it is considering a wide variety of applications."

In addition to the alleged 3D stacked RAM, the outlet also said that the PlayStation 5 will be out "3 - 5 years down the line."

The rumored release date seems plausible, The REM said, citing the PS3 and the PS4's 6-year gap.

Little else is known about Sony's next PlayStation reiteration but Tech Radar has a slew of notable rumored specs and features of the game console.

According to the outlet, the PS5 could still stick with disc drives, no matter how old school. Tech Radar quoted Ben Wilson, ex editor of Official PlayStation Magazine as saying:

"People love their boxed products, and 'experts' have been predicting the 'imminent' demise of the CD for more than 20 years. Remind me how that one has turned out? There will always be those who prefer special editions and sexy packaging to invisible downloads, and it's those guys and girls who'll ensure disc drives live on within gaming in some form."

Tech Radar also said that virtual reality (VR) gaming might be the norm five years from now. The future of VR gaming is also cemented with Sony's Project Morpheus reveal - hinting that the PS4-maker has plans of heading to that direction.

Another inevitable thing is a "cloud-based" future - especially with Sony launching the PS Now. This may raise eyebrows as delving too deep into that future would mean no more disc drives and disc version for games. In fact, such "cloud-based" future could even get rid of the PlayStation console altogether - with gamers only needing fast and stable internet connection to play their favorite games.

But, if such era should exist, it probably won't be anytime soon as Tech Radar noted that the PS Now is still limited to US PlayStation game console owners, leaving an international release date up in the air.
