Devices tend to drop in (retail) price about 6 months after launch, depending on the type of device.
If its a feature phone, there isn't much changing in that realm, so they usually stick it out for a while longer.
Smartphones, on the other hand, are evolving pretty darn quick so its possible that you could see it take a price drop in 5-6 months. Popularity will really be the big determination in price drop, so watch for the popularity of new devices in about 2 more months and the RAZR might drop a bit.
