In August, Sony announced its launch window line-up, which included 33 games – but has since been trimmed due to a few delays. When the PS4 hits Japan on February 22, it will support some games not included in the North American list, such as the beta for Final Fantasy 14: A Realm Reborn and indie darling Hohokum.
The Xbox One launch-day lineup announced in August overlaps with the PS4's, but includes Need for Speed: Rivals, Ryse: Son of Rome, Skylanders: Swap Force, Dead Rising 3, and a few more exclusives and outliers.
Update: An hour in and Sony has already added four games to its launch lineup: Skylanders SWAP Force, Super Motherload, Tiny Brains and yes, Warframe. Sony also added DC Universe Online to the list.
Update 2: The UK launch list includes two extra games, black-and-white indie puzzler Escape Plan and Flower predecessor, Flow. The UK list doesn't yet include the games added to the North American list.
Update 3: Sony has moved a few games around on the list. The revised North American list can be seen here.
