Last year no one believed me (and I was moderated for trolling) when I reported that Zipper Interactive was going to be shut down by Sony just weeks before they officially announced it. I have also revealed a lot other stuff way before they've been officially publicized (e.g. Next Generation Portable) and I now I have a list of confirmed games that are going to be showcased on Sony's next-generation PlayStation. The event will highlight the new hardware with a prototype model (and controller) that are going to be displayed.
Without further ado, here's a list of confirmed games (thus far) that are going to be shown at Sony's Feb. 20th event:
Electronic Arts Battlefield 4 DICE Madden 25 (for next-gen hardware) EA Tiburon
Epic Games Real time demo to be shown of Unreal Engine 4.0 running on hardware
Sony Computer Entertainment Gran Turismo (6) Polyphony Digital KILLZONE 4 Guerilla Games
Rumours are circulating that Respawn Entertainment's project may be shown in the event but may be saved for Microsoft's E3 Press Conference instead. SCE will have more 1st- & 3rd-party developer studios to showcase its games running on the next-generation PlayStation as the event is still being prepared. Gossip says Sucker Punch Productions is ready to show its next-gen project. Ubisoft is planning to showcase a title running on the next-gen PlayStation (presumably Watch Dogs I bet).
No mention of Capcom, Konami and SquareEnix releasing demos.
