Never. Why would prices ever drop? RAM manufacturers know what they can get away with now, because everyone needs the products this cartel is making. They also know that current prices are nowhere near the maximum of what a captive market will pay for.

Don't get your hopes up with China either. Demand is so high that Chinese RAM can be barely any cheaper or cost the same and still sell out. They have no interest in reducing prices either, especially since it's extremely unlikely they are making a profit yet.
