1. XNA 3.0 goes live - After a relatively short beta, XNA 3.0 goes live, and soon to be following is the community games feature, which lets XNA games get hosted on Xbox Live and sold for cash-money. Real, cold hard dough. This is sure to be a killer feature for XNA.
2. C# 4.0 - We finally get word on the new features planned for C# 4.0. The short list focuses on a few things: dynamic language support, optional / named parameters, and covariance / contravariance. The dynamic support looks to be most useful in general applications for duck typing, although after a discussion with Superpig I'm of the opinion that compile-time duck typing would have been more useful. Also, it sounds like the C# compiler is being rewritten entirely in C#. Take a look at the end of the video for an impressive demonstration of a REPL loop in C# using the new evaluator.
3. Direct2D - Microsoft announced a new native API for game development. Built on top of Direct3D, Direct2D is designed to make two dimensional graphics easier and faster than GDI and GDI+. This might be a killer for SDL on Windows. The reason I find it interesting is because we'll probably be pushing this into SlimDX as soon as possible.
4. Visual Studio 2010 CTP was released as well. I've downloaded it (it's absolutely monstrous - 11 parts at 700 MB a part) and it seems to be quite interesting. Most (if not all?) of the interface has been rewritten in WPF. While it does have its downsides (font rendering), this also means that certain features may be coming to C# applications, such as the VS text editor. This would be quite awesome indeed.
That's it. There is no more. That's all she wrote.
