It's different with other companies. Sony cannot put Resident Evil 5 (for example) on PSN without having the permission from Capcom. If it's a Sony prodcut then they can add it any time. Why do you think it takes so long for them to add PS2 and 1 classics to the store? Why do you think the store gets updated every Tuesday? It's because they need consent when adding games that aren't theirs, etc.
