I just found out that Microsoft will release what it seems to be a very powerful tool for game developers: XNA Studio. They have announced it at the Game Developers Conference in March (so, maybe I'm a little late telling you people this "news").
I'm just posting this here because I got really excited about it! It seems that it will be an awesome tool. I read that it is based on the Visual Studio 2005 Team System, and for what I've checked in the beta version of VS 2005, that is a great tool. Anyway, just so you know about it. :)
