Wow this something I never expected. I honestly don't know how to react, I don't follow PlayStation religiously or anything but I still watch their big events out of interest. But man what does this mean? I mean in the long term it could be something positive out of preparation for the PS5 like Nintendo did in E3 2016 before the Switch. But short term wise it was not great for Nintendo either and at least they had something to excite fans on what is the biggest video game event of the year.
I guess E3 will be between Nintendo and Microsoft next year... that'll be fun.
