According to an alleged email leak, Sony plans to fully unveil its next-generation PlayStation 5 console at a special event scheduled for February 12, 2020, supposedly dubbed PlayStation Meeting.
According to the leak, Sony has sent out invitations to several publishers, including the likes of EA, Activision, and Ubisoft.
The leak also alleges Sony is investing anew in virtual reality (VR) technology following an uptake in interest after successful results developing a PSVR 2 prototype. It purports in-earnest marketing of PSVR 2 will begin before the end of 2020.
Note: Take this with a grain of salt. Although it makes sense (considering it worked for PS4 and the timeline lines up), waiting on Sony before jumping for joy is the best bet. For now, just treat it as a place to discuss the possibility and I'll update it (or create a new thread) if any admissions or denials are released.
