Label don't matter. It can be called E3 or Gamesfest or anything else as long as there is a showcase. Essentially this just means Sony is not paying a middle company to host a show, and they are doing it all themselves.
This year is sorted pretty much. Probably will get a little more on Horizon, Stray, TLOU2 PS5 edition launching with DLC and MP mode and will close off with a GOW trailer. However main focus will be on end of year and end of spring.
Wonder if Ghostwire Tokyo will get less love now that they are owned by MS.
