I am having the same issue, its 7:51 pm CST. Cannot get disk benefits. This is the 2nd time I have gotten a game and the Disk Benefits not work.
This also happend with Ratch and Clank: Full Frontal Assault Cross-Buy, it was supposed to release for the Vita on Jan. 29th, but Disk Benefits still isn't working. I hope the same doesn't happen for Sly Cooper....
No, the game is released on Vita. It just doesn't work for some reason. The Vita version of FFA is not out yet.
