It's already begun, the black figures in the image seem to be teases for some of their announcements.
We have more in store for PS3, Vita, and even PSP fans in the coming year, so be sure to keep an eye on PlayStation.Blog, as well as our Facebook and Twitter, for any announcements (not to mention the inevitable pre-announcement teases!).
The one in the top left appears to have been figured out already, Senran Kagura for Vita.
Edit: And the silhouette on the right is apparently from Akiba's Trip 2. That leaves the one on the bottom left. And XSEED will likely have some other teases for non-PS platforms (probably 3DS and PC) before too long too.
