Nintendo Europe has distanced itself from strong "rumour and speculation" surrounding a new DSi Speak Channel.
It all started on the Nintendo customer support website, where GoNintendo spotted the following line:
Redeem a Nintendo DSi Download Ticket number, such as for the Nintendo DSi Speak Channel, enter the number off the Nintendo DSi Download Ticket in "Settings and Features" off of the main Nintendo DSi Shop page, then select "Nintendo DSi Download Ticket."
The Wii Speak Channel uses the Wii Speak microphone peripheral to allow people to chat together and in separate rooms if they wish. Mii avatars attempt to mouth what you're saying. You can also leave audio clips on message boards and record audio captions for pictures.
It's that exciting.
