I would be surprised, though, if it never happens. Funcom has offered bonus-point days as well, where you get discounts on their cash-shop currencies and such. Nobody can say for sure it's happening, of course, but I wouldn't be surprised if it does.
I could see these cash shop prices being this high if the game were f2p. But its buy to play....for 60 bucks! If it were completely free 2 play i'd throw down 20 bucks for a few re-textures.
