An anonymous reader writes "Sony and Microsoft's next-gen consoles are coming: too many "next generation" games announced, too many details have leaked to suggest otherwise. But while Microsoft and Sony officially keep schtum on the existence of the Xbox 720 and PS4, both companies have laid out some of the next-gen features you can expect from both already. Microsoft's recent IllumiRoom demo showed CES visitors how an Xbox might use a whole room as a screen to play on, while Sony's purchase of game streaming service Gaikai points to a future where every Sony device might be a PlayStation, not just the PS4. It's an interesting rundown that leaves you wondering just what secrets both gaming giants might still have in store for us."
