I'm not sure if it has been mentioned, but the PC requirements for M22 are exactly the same than M21. So yes, old gen.

The issue I have is that, from what I heard here and there, animations are totally different, to the point that the gameplay is different. So it's not only "better graphics" (I can live without them), but "different game", so probably missing features, AI reactions, etc.
