So this is the tech preview. If I love it (I'm not even through the
presentation yet, but like what I see) then when can expect to be able
to use it in a production environment I've taken on responsibilty for
setting up the build environment for the studio I work for, and want to
be able to tell my boss when this solution will be available for
production environments.
Or this not released information

XNA Release
Kent Waldrop Ap07
Yes you can use Team Foundation Server's Team Build feature to enable automated builds today which are based on MSBuild. XNA Build builds on top of the MSBuild project format so there will be an easy migration path from MSBuild to XNA Build.

We're glad you like it! This tech preview is our first public pre-release of XNA technology and our first chance to get feedback on such a large scale. At the moment we don't have any update on our timeframe for an official release, which is pretty standard when the a product group conducts its first pre-release. This is our opportunity to see what you think and get the feedback we need to continue building the product and making it as useful as possible for your studio and for other studios.

Great JOB! Microsoft is building the future on services to the clients!
Once I’ve read "MSbuild" on "MSDN", I was able to understand XNA.
Today too many people mistakes the XNA true meaning.
So much people has the Whrong first-impression as if it is one engine like others.
Once he understands, he say: Amazing!!!!! Cool!!!! Great!!!
The "Face" it shows!
The first impression is not yet so good, as .NET FX was unrelated with .NET 3.0 at First Sigh.
This XNA will integrate everthing... back compatbility is the way!
Older Softhouses will release new versions of theyr old 3dfx games that doesn’t run anymore on XP!
As before in the Glide.dll, like my Motorhead racing, Hi-octane... ah.... they could release this again.
THAT’S IT You did it. that was inpressive! CLAP CLAP CLAP!
Plugins that alows INTEGRATION tools like Visual DirectX, OpenGL, are the best aspects of the XNA to Show!!!
Thanks! Please keep going. don’t lose this patch!
I'm looking for a rapid access and aceleration on Game Development Environment that Microsoft will bring to the future of our PC!
As It Make games more acessible, to New Developers, More game developers born, To Old Developers, More Effort on Stabilished Softhouses to bring more Game Quality!
And more people playing! And programing!!!! WAY WAY!!!
