Activision has officially announced Tony Hawk's Motion for Nintendo DS, and, in doing so, also confirmed rumors that the game will be controlled using motion-sensing. The game will utilize an accelerometer-based "Motion Pack;" we're checking with Activision for more details on the tech (for instance, does it occupy the GBA slot?)

According to Activision, players will be able to "twist, tilt and turn through various skateboarding sessions." iPhone much? Also, as a first in the series, the game will introduce snowboarding – wait, what? Yes, "Tony Hawk," a name synonymous with ... snowboarding. Tony Hawk's Motion will come bundled with Hue Pixel Painter, an action-puzzle game that has players tilting the DS to "return color to a dull world." Both games are being handled by Creat (makers of the [ahem] superb Aqua Teen Hunger Force Zombie Ninja Pro-Am) and will hit in November. Check out the first screens below.

Update: Activision has confirmed with us that the Motion Pack is a proprietary add-on developed for it by Kionix, Inc. and fits into the DS' GBA slot.
