It looks like the Applications store is open on iTunes and I was able to do the update to version 7.7 to download the apps. The new iTunes seems to be ready for the little Remote application that you can use to control iTunes and your Apple TV from your iPod Touch or iPhone via wifi. That sounds pretty cool.
But, the new software update doesn't seem to be able available yet to actually make the app work on my iPod Touch.
Here's the link to the app store if it's not showing up in your iTunes for some reason.
