Unconfirmed reports from Japanese retail sources suggest that Nintendo is planning to roll out the DS handheld on November 4th priced at 19,000 Yen (140 Euro), followed by a US launch on November 11th at $179.95 (145 Euro).
The retail prices suggested in this report would almost certainly make the NDS significantly cheaper than the PlayStation Portable, which is expected to cost well over 30,000 Yen (220 Euro) when it arrives in Japan later this year, ahead of a US and European launch in 2005.
