Yep. I found this:
Our DS’s(DS’es) are meant to play games. The Zune is meant to play music. Then why is the Zune’s games looking better than ours?
Why are these so nice looking? Ok lets push that to a side and look at the iPhone/iPod Touch. Why does it have no games? There should be games when the 3rd party apps come out but no. Surprisingly Apple have not included any game right?
At GDC 2008, Microsoft announced plans on enabling a community publishing pipeline for the Xbox 360 and Zune. Before this XNA wasn’t too popular. Ok so the Zune brand was launched as a mobile entertainment platform rather than a strictly audio platform and will continue to evolve and expand. But still! The DS should have better capabilities than the Zune!
Microsoft confirms Zune will play games by July 2008.
The Zune’s touchpad will hopefully make for a decent controller. Graphically, Zauri, the only game demoed via video, was simple in nature, but the addition of music library support could make for interesting shooter gameplay.
