Those worried about needing a bigger hard drive after it was revealed that Call of Duty: Ghosts would need 50GB of space on the hard drive, and Knack would need 37GB shouldn’t worry – while it needs that space, it won’t take it up, simply caching the install instead.

That means as you play, it will install and delete data, saving you a lengthy install time and valuable hard drive space. Essentially then, you’ll have at least 400GB of space on your hard drive to do what you want with.

@DiamondDM13 it’s automatic, not install but caching data — Shuhei Yoshida (@yosp) October 26, 2013

This makes a lot of sense, actually – it’s a smart way for the PS4 to do things, and the box sleeves saying that X space is required are still true – it doesn’t say anywhere that it will use up that space.

So, we can all breathe a sigh of relief now, and try to ride out November while we wait for the PS4 to arrive.

Another interesting tidbit of information is that the PS Camera isn’t actually required for voice commands – you’ll be able to shout into your mic attached to the DualShock 4 instead.

UPDATE: This has been confirmed in the official PS4 FAQ.

When playing disc-based games on PS4, do I need to install data to the hard drive? Yes, all PS4 Blu-ray Disc games must be cached to the hard drive to ensure a smooth gaming experience. However, certain titles may not require you to wait for the game data to be fully cached before starting gameplay. In order to start playing disc-based games, users will need to insert the game disc into PS4 just like on the PS3 system.
