If you've got a hunger on you for a preview of the next generation of the Visual Studio development envrionment, you can download the Community Tech Preview of Visual Studio code name "Orcas", which is the flavor of the course that will follow Visual Studio 2005.
Orcas was discussed in this morning's TechEd Europe: Developers keynote, and a number of "Orcas"-era technologies - notably the Language Integrated Query Framework, or LINQ, will be presented in detail over the course of this conference.
Orcas is quite a serious feed - it clocks in at about 3.7GB and comes as a Virtual PC image in response on customer feedback - but there is a download manager that will assist you in obtaining it.
To whet your appetite, here are some of the new feature highlights in this Orcas September CTP, which you can download at this link:
p.s. 'Ocras' is the Irish word for hungry, or so I'm told :)
