A few of my guesses
1) will be multiple plaforms, From a mobile like device, handheld device/ cheap console to an Expensive console/pc one.
2) They stated that their is going to be an Windows Os variant that will feel more like an Xbox Os for potential PC gaming handhelds etc;
3) we don't really see the discussion happen a lot but in Europe they are pushing court cases against Sony because they't don't allow other parties to sell digital games for PS consoles. What it basically means is that potentially at the end of the year you can see Amazon selling FC 26 PS5 keys for 55$ or you buy an humble bundle that comes with keys that work on Playstation but just like Steam Sony will not even get a 1€ cent from those keys. The reason I mention this is because your COD (warzone) account can be played on Pc, then on Pc and then on PS without you having to spent any cent on it so I expect MS will try to sell COD main game from the COD app without giving any cent to the platform holder.
