The relevant passage reads, "The coming months will be exciting and full of surprises with the release of highly awaited games such as Blood Bowl, TrackMania DS, Runaway on DS and Wii, or even sport games dedicated to major events such as the Tour de France." (Emphasis added)
There has been no official announcement of the game. Shacknews founder Steve Gibson, who recently purchased a Nintendo DS and is known to go weak in the knees at the mention of TrackMania, has yet to be informed of today's news.
Update: It appears the previously-embedded trailer is illegitimate!
This is very interesting. I wonder if NADEO is the developer...

According to the video on the 1st link the developer is indeed NADEO.
