Sony plans to release a new hardware revision of the slim-line PlayStation 2, according to Japanese publication Nikkei Business Daily. The new model differs from the current slimmed model only by a new designation code of SCPH-79000 and a lighter weight. The main console hardware itself for the SCPH-79000 model drops in weight from 900 to 600 grams, and the system"s AC adapter falls from 350 to 250 grams. Nikkei reports that the system"s considerable weight savings were achieved by Sony reducing the number of parts inside the machine. The more efficient hardware revision is also suspected to cost less for Sony to produce, giving the company even greater flexibility to drop the price.
