Microsoft has released a PC specific technical preview of their Kudu Game programming software.  Their goal was to add PC specific features.

From their PC build 1.0.48 is live! blog entry:

Hey everyone.  We’ve been working hard to add a bunch of new PC specific features to Kodu.  Mostly we’ve been focusing on making keyboard and mouse control more useful.  Plus there’s a bunch of bug fixes.  We think you’ll like the changes.  Let us know!

Kodu is a new visual programming language made specifically for creating games. It is designed to be accessible for children and enjoyable for anyone. The visual nature of the language allows for rapid design iteration using only an Xbox game controller for input (mouse/keyboard input is also supported).

There are some specific system requirements to be aware of as well:

Supported Operating Systems: Windows 7; Windows Vista; Windows XP

A graphics card that supports DirectX 9.0c and Shader Model 2.0 or higher is required. .NET Framework 3.5 or higher is required. XNA Framework 3.1 Redistributable is required.
