I'm really looking forward to the Xbox One's UI. I'll really appreciate the improvements in speed and efficiency.
And, available tomorrow (9/, will be PS4's 3.0 update with a good amount of improvements.
- Sharing video clips to Twitter
- A dedicated section for PlayStation Plus - (Something I think is way overdue.)
- YouTube live - (I was wondering when Youtube Gaming would be integrated.)
- PNG Screenshots
- A new hub for Events has been added to PS4
- Improvements to Messages and Favorite Groups
