For me, announce that BC will also increase games resolution and frame rate WITHOUT the need of a developer patch.
Like being able to play GTA4, Mass effect trilogy, Dragon Age origins and others on launch day at 1080 60fps.
I doubt it will happen but it would be a game changer for me.
I'm pretty sure that is what both XSX and PS5 are going to do minimum (it's what XBX and PS4 pro do too)
But it's a case by case situation. Games hard-locked at 30fps will not get a jump.
