Honestly, PlayStation is in a great position but they need to be super pro-active. Particularly on the exclusive front.
They have plenty of money now, with almost 8 billion in profit due this year and I think they should use all of it to re-enforce PlayStation.
Buy Capcom, they are a steal at a little over 2 billion... Monster Hunter, Street Fighter, RE, DMC, a new 2d Marvel vs Capcom etc.
Get Kojima to sign on to WWS.
Port SFV to PS5 as a launch game.
Lock down another From exclusive .
Target CDPR or Bungie as another large acquisition.
That would be my plan.
Maybe buy some smaller studios too, like Housemarque.
If Bungie or CDPR didn't want to sell, try Remedy..... or IO.
