While the PS4 will go on sale in North America on Nov. 15, European sales won't start until Nov. 29.
The PS4 will support 33 games by year's end. 15 of the titles, including major releases such as Battlefield 4, FIFA 14, Assassin's Creed Black Flag, and Call of Duty: Ghosts, will be available both via disc and download. The other 18 will be download-only. The Xbox One's launch lineup was announced earlier today.
To convince PS3 users to upgrade (and give a lift to a weak console hardware market), Sony says it will offer "significantly discounted" digital copies of PS4 titles to gamers who have already bought the PS3 versions.
Sony also discloses gamers will be able to broadcast their gameplay simply by pressing a "share" button on their controllers, thanks to a partnership with streaming service Twitch.
