Orcas is now Visual Studio 2008
The official name of Orcas is Visual Studio 2008. The .NET Framework with this release is .NET Framework 3.5
Multi-targeting support
In previous releases, VS only supported a specific version of .NET Framework. Eg: VS 2005 supported .NET 2.0, All this is going to change with VS 2008. VS 2008 is planning to support "Multi-targeting" - which will allow Visual Studio to target multiple versions of .NET Framework.
When we create a new project or open an existing project we can specify which version of Framework we want to work and IDE will enable appropriate features and compilers. One thing to note is the VS 2008 multi-targeting support only works with .NET 2.0, .NET 3.0 and .NET 3.5 - and not against older versions of the Framework.
Javascript Intellisense
In previous versions of Visual Studio, writing Javascript code has been a pain without much intellisense support from the IDE. VS 2008 addresses this pain point with great support for Javascript intellisense. This feature will really make Javascript developers happy.
Scott has a nice blog on this topic.

Comments
Hope I can get my hands on the VS2008 officially :P .
I wish .NET 1.1 is supported, cause most of the projects are still maintained under older framework.
