Xbox already lost one console war over plans to stop the second hand market so they know how important it is to players. Their new disc to digital feature is proof they are looking at Sony's mistakes and slowly moving in the opposite direction. It basically removes the most serious thing that made physical games less convenient.

If the PS6 is digital only and Xbox doubles down on discs it might be a slam dunk victory. Not all players understand or care about it now, but if they explain it well in the launch window and combine that with their back compat history I think they have a good chance to win.

Even Microsoft knows that gaming is a competitive market and pulling customers from PlayStation is better than trying to extract as much as possible from your existing user base. One Game Pass sub is worth more than marketplace fees from 3 extra games you would normally buy used.
