Rumor about Japanese 3DS date

According to Twitter user "nocchisan", who claims to be working for DS-peripheral maker Keys Factory, his company will be releasing some peripherals for the Nintendo 3DS on November 20. After stating that, nocchisan went on to say that people that are "buying the 3DS, buy it at the same time!"

So we should buy their stuff on November 20, the same day as we're buying the 3DS? Interesting! Nocchisan's Twitter account has since been deleted and Nintendo ain't talking.
