I can't connect from my PC right now (proxy not handled by the PC PSN application), but did the packs prices after gone down since the release ?

The packs were way too expensive (4 ships and 4 tracks for almost 2/3 of the game price), but I though that they would be cheaper after a year.

Cheaper ? Still not ? if that's not the case, I definitly hate DLC and Downloadble version of games (cannot lend, cannot bring it at a friend to play instantly together, cannot re-sell it as "used" and generally the same price as UMD/BRD version).

I fear the DLC for WipeOut HD.
