Please define next gen game standard...

I am working on a small project with 2 friends using Unreal Engine 4. Our goal is trying to make a releastic scene with features in UE4.

And we want to achieve some so called next gen features as well. However, we find it is hard to define what is next gen standard.

As far as I know, at least, 4K res texture is required and one of my friends has been working on multiple layers of textures at 4K res already.

Also, UE 4 provides pretty advanced material but it can be achieved even in UDK(UE3). So I don't really consider those as next gen features.

And here I come to ask you guys about any ideas about so called next gen game standard.

Edit: I wanted to see people talking about their ideas about what a game can achive. But what I saw here most were trolling.

Didn't I mention that we are only a 3 guys group on a small project to make a scene instead of saying we are gonna release a full game only for money?

You guys are so good...
