Games already out that are Windows arent gonna get any love, with a few exceptions.

SOS/PS4 development being similar means that new games will likely get love in the future. People who still make just "Windows" games (no console version) have already been moving the Linux direction.

Multiplatform PC games are already ported from console to Windows most typically. Games will actually port easier and better from console to SOS, particularly PS4.

Plus Windows has accumulated too much internal bloat, same game on SOS will run much faster once the kinks are worked out. SOS will be closer to console performance for the same hardware.
