While some customers are likely still using the Vita and/or the PlayStation 3, I think it's safe to say that a lot of them are probably gaming on a PS4 these days.
Additionally, during the media event, Sony revealed that PlayStation 4 sales have reached 106 million units worldwide, shifting around 3.5 million consoles during the holiday season. However, iet does also demonstrate that PSVR sales have plateaued and started to tail off.
The success of PlayStation VR has been intertwined with the success of PlayStation 4, with so many consoles in people's homes its an easy add-on for gaming fans.
We were really hoping to see the PS5 at CES 2020 but Sony PlayStation President Jim Ryan has ended his press conference at CES 2020 teasing that "there's plenty to share about the PS5 in the months ahead".
In the last quarterly report, the number of PlayStation 4 sales was at 102.8 million to surpass the original PlayStation's 102.49 million. Maybe Sony has anticipated fans will go insane if they don't throw us a bone, so they did reveal some exciting details about their incoming console. He claims "I expect PS5 to outsell Xbox Series X in 2020, but for both platforms to sell more consoles at launch than both the PS4 and Xbox One did back in 2013". Patents have surfaced regarding possible PlayStation VR 2 designs including built0in cameras for inside-out tracking or wireless options.
Some of the PS5 specs have finally been revealed, but we already speculated Sony would add 3D audio support and an SSD hard drive. Until then, we'll at least have something to laugh at.
