So just name something that you think you'll enjoy on next gen that might not have been possible on current gen consoles such as PS3 and Xbox 360 (and Wii U...KIDDING!)
It can be anything. Maybe your favourite new thing is the faster User Interfaces. Maybe you're a graphics whore and the feature you like is the fact that the consoles are more powerful and therefore games will look better. You don't only have to list one thing, you can list multiple.
What I personally like is the super fast and responsive UI. I can't speak for the Xbox 360, but on the PS3 it is sometimes very slow, especially when you are in game and are trying to read or send a message to someone. It can surely test my patience. Another thing I like is the fact that because the consoles are more powerful, most games will feature 1080P resolution. I currently got into PC gaming and tested out many games playing 720P and then changing to 1080P. The difference is night and day, 1080P blows it out of the water. Not sure if consoles will have the same difference in 720P and 1080P but if they do then I am super excited. I also think that as the gen progresses we will see many more 60 FPS games, which is always a plus in my book.
What about you guys?!
