A mysterious tech demo has been spotted at Nintendo's partly constructed booth!

At Nintendo's almost complete booth, a sign that's spotlighting a DS testing station has been spotted. On this test station, players will be able to experience something called the 'DSpeak Tech Demo'.

Although actual details are unavailable, it is confirmed that the images on the DSpeak sign featured Mario on the upper screen of a photo of the Nintendo DS system. Perhaps a simple text to speech demo? Or possibly a way to send voice via the DS's microphone? We'll have to wait and see!

Stay tuned!
