It's not here yet but Sony is really talking it up.
Firmware update 2.00 for the PlayStation 4 will greatly enhance the system's capability and appeal, as indicated by a new preview posted over at the PlayStation Blog .
First up is the ability to listen to your own music when playing games. You just load the music onto a USB drive and take advantage of the USB Music Player feature that will be included with the new update. MP3, MP4, M4A and 3GP will be supported, but the files will have to remain on the USB drive if you want to listen to them; they can't be copied to the system's hard drive.
Sony will also improve the main home screen. The PS4 will now limit what it displays to your 15 most-used games or apps, and the rest will be stored in the Library section. Thankfully, the Library will be updated to let you filter and sort at will. And of course, we'll get the previously confirmed features as well: Theme support, the chance to spruce up your background with a bunch of different colors, and a "players you may know" area in the What's New section. We also get improved voice commands, enhanced live streaming, and a new way to back up PS4 data (from settings and saves to video clips and downloads).
And oh yeah, Share Play is coming, too. Man, this update will be epic .
