Just look at the date and the Event " Experience PlayStation January 14, 2020 - February 16, 2020 "
It literally said "Celebrate 25 Years of Play with a collection of titles on PS4 and PS VR" which is suspicious because they had that last year, and this year supposed to be 26 not 25 it probably a replaceable info that will be unveil
Also a lot of Sony Head from upper management already arrived in US from across the Globe. Including Shuhei Yoshida, Hermen Hulst , etc .
