found a few articles having to do with the Tegra. PC Perspective
found out that the Zune HD will indeed have the Tegra from Nvidia staff at Computex.
Relatedly, the tegra was used in an augmented reality demo game to shoot zombies! Funny thing is they use Skittles in the real world as bombs, differnt colors are differnt types of bombs. Could this be the kind of games we might see on the Zune HD. My guess is as good as yours, but i think it could def be something we might see on windows mobile 7 devices.
