Sony's launched a new video promoting the PlayStation 4's interface, specifically showing off the ability to pause one's game to check out shared videos and the PlayStation Store. You can hold your game, go start a download, and resume play. Neat.
The other interesting bit of information is the ability to download games in parts, rather than all at once. The handsome gamer in the video, who I've decided to name Chase Glistener, is given a choice to download the single-player and multiplayer aspects of Killzone: Shadow Fall separately, so he can more swiftly jump into a game with his online friend, Romulus Salamander.
There also seems to be some sort of love story between Chase and a woman I'm calling Malfeasance Brickfist. The implication seems to be that playing Knack on PS4 will make all of the girls want to do a kissing on your face.
Of course, the cynic in me suggests nothing in the video will be as sleek and quick as it'll be in real life, but after dealing with the PS3's slow-ass, convoluted interface, it's definitely looking to be a step in the right direction.
