WTF?: PSN Pricing

Alright, can someone tell me what the hell is going on over at Sony Headquarters? I turn on my PS3, go over to the Store and what do I see? A whole clusterfuck of confusion. $6.99 here, $22.99 there, what the fuck is that about?! Here's a quick breakdown of what I'm talking about.

Patapon 2, which just came out not too long ago is selling for $19.99. Reasonable. Pursuit Force 2, which has been out since January 29, 2008 is $22.99!?

Call of Duty: World at War map pack is $9.99, which includes 3 new maps, a new zombie mode, and other enhancements. Not bad. The Killzone Flash and Thunder pack includes 2 maps only and costs $6.99!?

PSOne classics usually costs $5.99. The recently announced Resident Evil: Director's Cut will cost $9.99, even when other countries are paying less for the same game?!?!?!!

Sony really needs to get on the ball and start making pricing standards or else developers will do what ever the hell they want, and potentially lose customers.

In the end, until its fixed, all I have to say is -- WTF?
