The current catalogue is huge (with a couple of decent gems still to come later in the year), and the prices appear to be coming down - in terms of added value at least.
Take SCEA's God Of War: Ghost Of Sparta bundle. That pack's due in November, and include a bunch of goodies for its $199.99 asking-price. Amongst the gubbins are copies of both God Of War: Ghost Of Sparta and God Of War: Chains Of Olympus. You'll also net Kick-Ass on UMD, a custom PSP-3000 and a 2GB memory stick. Considering the extras are probably worth a good $80 on their own, the package seems fairly reasonably priced.
