“Series of Massive Significance” Coming to PS4, According to OPM Tease

Something big is going to be announced for PlayStation 4 in the very near future—that is, if a recent tease in the latest issue of Official PlayStation Magazine isn't just yanking our chain.

According to the magazine (via NeoGAF), "Next month's cover is one of the most exciting in OPM history, with a series of massive significance finally being confirmed for PS4."
 

What do you think and/or hope this "series of massive significance" could possibly be? I for one would love to see a return to the Jak & Daxter franchise, even if Naughty Dog isn't at the helm.
