Things they can chance can do better in Uncharted 4.
1. The enemy KI- well the enemys arent stupid in Uncharted 2 or 3 but they arent intelligent either. And with PS4 this point will be handled well i think ( even The Last of Us showed us next gen KI)
2. no scenes where thze enemys are so loyal that they fight against Drake even when the ship is sinking with them
3. wider Levels ( not open world but also not that linear like Uncharted 2 and 3)
4. more sneeking opinions
5. improved combat ( more moves, new moves)
6. There shoul be scenes where Drake can shoot a wall and than can climb on the wall because of his shootings
7. an diving level
8. an Motorboot or Motocross action scene would perfectly fit to Uncharted
