In their latest FAQ, Sony has assured gamers that the PlayStation Store, when it comes back up, will be updating more than its typical once a week.
To try and make up for all the missed release dates, like the MotorStorm Apocalypse demo and Under Siege, Sony will be updating the store's content multiple times a week.
Once the store goes back up, the "Welcome Back" program will go into effect. Gamers in Europe will be able to download two PS3 games and two PSP games, albeit from a short, selected list.
