I told you more good things were coming: XNA Game Studio 3.0 Beta has gone live. This is a huge update to the XNA development system, and delightfully includes support for writing games for the Zune media player. Yup, don't let those fruit-themed phone guys have all the fun, and get your SpriteBatch running in your hand.
You can download the Beta here.
Note: this beta doesn't support running your apps on XBoxes, only Windows. Yeah, that kinda jibes with the Xbox goodness story, but at least you can get your applications ready and start to explore the new features. If you are in the middle of a Xbox game at the moment, stick with Game Studio 2.0.
