This week's PSN update is now live! The PSN fall sale starts, which sees several titles on PSN discounted, more so for PlayStation Plus subscribers. Additional goodies include full downloads of Ratchet & Clank: All 4 One and Saints Row 2 -- the latter is available free of charge to those who have redeemed their Saints Row: The Third pass.
Then there's the avalanche of DLC for Ultimate Marvel vs Capcom 3, Batman: Arkham City and several other new releases up for consideration. For the fairly massive list of what's available on PSN today, hit up the PlayStation Blog.
