If you are in the mood, you can pick up LittleBigPlanet Vita now before street date. Don’t worry, it’s officially okay to pick up the game at the store as this was said on Sony’s part. While you can’t do anything online till tomorrow, which isn’t bad. They say:
Production on LittleBigPlanet PlayStation Vita was completed earlier than expected, and due to the excitement from our retail partners, some have decided to put it on shelves as soon as the product was received.
You’ll still be able to fully enjoy all the offline features of the game, but the servers will not go live until September 18th. We apologize for any confusion this may cause and will keep you posted on any further updates.
The original date for the game was September 25th.
