Will RAM prices ever go down?

I'm going to be honest and say I don't know much about hardware.

I want add some more RAM to my PC, but I'm not sure if I should wait for lower prices. I don't need the RAM urgently, but I'm not sure if prices will go down enough in the future to justify waiting for months or years.

Do any of you expect that there's going to be substantial drops in RAM prices within the next year?
