I'd rather see consoles be limited to what they can handle than a game to be limited for everyone because of what a single console can handle.
I want this game to be huge and look beautiful. If my PC can handle 60fps I don't want to locked to 30fps because that's all an Xbox can handle. And if I want to play it on an Xbox I don't want it to be a blurry mess to get 60fps, I want it to look as good as it possibly can. Especially in a game like this where the visuals do a great majority of the storytelling when it comes to exploration and finding new things.
