If you were worried that you just would forget, looks like you might just be luck to score some cool Killzone 3, or Littlebigplanet 2 DLC.
As of midnight all the PSN items went from “Coming soon” to available. It’s not currently known if this was meant to happen or a horrible glitch they will need to sort out earlier. Since the dynamic theme didn’t come out yesterday, anything is possible. This might be worth the effort to get your Home item, or in game DLC while they last!
