*I am going to copy paste my previous comment on another topic from PS5 rumor *
You guys late for the April fool
Btw this is what we call company deception in confusing their competitor (Microsoft ) , by revealing fake info on the internet. Nowadays info are easily acquired in many ways, even a casual people will get it on forum and social media. With this fake info, Microsoft and Nintendo will be deceived.
The developer (some developer close to SONY/ or their own Studio ) probably has the dev kit, it's the prototype dev kit. It does not mean the spec is the final spec and it does not mean it close to it's release date. Because like previous consoles, they had many prototype and many early version that changed overtimes prior to release date. Because they need to make the games, and that games need to be made in 2 or 3 years times periods.
PS4 is selling Like Crazy , and it will be selling more in 2018 and 2019 due it's first party exclusive and 3rd party deals. That's not even include of price drop possibility. How come they want to completely kill the potential sells of PS4.
Navi is not yet release and Ryzen APU is just out, the price is still very expensive , even thou it's cheap compared to their competitor (Intel), It's still very expensive if we want to included Navi GPU. Also consoles price are targeted at 500 USD to 400 USD, SONY probably waiting another year for better price and optimization.
So i don't see any possibility PS5 coming in 2018 , even i don't a see a potential sales at 2019. 2020 is a perfect year for SONY , with reveal date in February 2020 like PS4 did and release at November or October 2020.
