Jason Zander has revealed the new UI for Visual Studio 2010.

Here are some of the features of the improved IDE:

Reduced clutter and visual complexity by removing excessive lines and gradients in the UX and modernized the interface by removing outdated 3D bevels
Placed focus on content areas by opening negative space between windows and drawing attention to the current focus with a dominant accent color and a distinctive background
Added an inviting new palette to make VS 2010 more distinctive
Triangle glyphs in the margin are used to collapse or expand your code blocks
Collapsed sections of code are marked with an empty triangle (pointing straight) as well as a set of ellipses
Colors on the margin indicate edits that have been made
• New Project dialog has updated to include online template viewing, a search box, and easier navigation
• New Extensions Manager to improve searching and installing VS extensions

It's looking pretty good. I can't wait for a new ctp or beta release to update The Future of Managed Code presentation.
