They're probably gonna pad the time between high profile releases with PSN games and the like.
Octodad is supposedly coming out at the end of January with Don't Starve coming in the first week (Jan 7th).
Beyond that, we still don't know when these PSN titles will be out and could possibly make it to PS4 within those months:
Outlast Galak-Z: The Dimensional The Witness Transistor Shadow of the Beast Secret Ponchos Cosmic Star Heroine Rime Everyone's Gone To The Rapture 1,001 Spikes Starbound Hotline Miami 2 FEZ (???)
I seem to remember reading that Abe's Oddysee: New 'n' Tasty Edition would be released in the Spring so there ya go. --- Think of the allergies b4 you applaud. Next time, just sit there & stare blankly at a person to express your support of something. -Madigari on PS4 @ E3 '13
