"Later this year, Zune plans to release free applications such as Twitter for Zune and Facebook for Zune, in addition to fun 3-D games such as "Project Gotham Racing: Ferrari Edition," "Vans Sk8: Pool Service" and "Audiosurf(TM) Tilt." Games can be added to Zune HD via Zune Marketplace over the Wi-Fi connection or when connected to the Zune PC software."

I wonder how PGR will work

does this twitter and facebook thing mean it doesn't even have a browser? if that's the case i can see why it will never even approach the ipod in sales.

They are separate apps like on the iphone. Every try using Facebook or twitter in a portable browser? not pretty

true, but with the way safari (or maybe the zune's browser too?) seems to work i'd prefer it over a dumbed down mobile version if it's anything like what is on my blackberry.

Does the Zune have motion sensors? Or am I getting the wrong idea about Audiosuft: Tilt?

It has an accelerometer.

here's a glimpse of PGR on Zune HD....
