If you haven't heard this news you must be living in a sensory-deprivation chamber. Or you're really, really busy at work (which probably goes without saying).
That said, the VS 2010 and .NET 4.0 beta 2 is now available for public download from MSDN. I like the MSDN format, but there's also a fancy product page with all sorts of beta 2 resources.
Channel 9 has a good video about installing the beta which is worth watching, particularly if you're installing VS with TFS which requires SQL Server 2008. If you're just installing VS without TFS, you can save yourself the 20 minutes and just go for the install. You'll want that extra time because the installation of VS itself takes about 30 minutes.
If you run into any problems, there are a host of MSDN beta 2 forums.
