Tuesday's PlayStation Store update is delayed due to extended PSN maintenance in some areas. PS Store updates usually occur on Tuesdays, but this week's additions are in limbo while Sony continues maintenance running over from Monday, April 15 in certain areas.

When the update does come, it'll bring a Soul Sacrifice demo, Sacred Citadel, Mad Dog 2, and others to PSN. While you may be able to sign into PSN currently, you won't be able to acquire these games until the Store updates.
