It looks like 20GB PS3s have gotten temporary price reductions from some Japanese retailers; Kotaku has pointed out a post on the Akiba blogs showing some retail chains in the country reducing the price of the 20GB model by 10,000 Yen, around $80. We know PS3 sales have hit somewhat of a lull recently, so stores may be aggressively reducing price to reduce stock levels. Continued price reductions can not be sustained without support from Sony; if sales continue to languish, Sony might have to reduce the price of the 20GB system even further.
