The new browser codenamed “Project Spartan” won’t be in it, but the March build of the public Windows 10 preview has a bunch of new features. Among my favorites:

• ARIA Landmark Roles,
• Web Audio API,
• @supports,
• CSS Gradient Midpoints,
• unprefixed Fullscreen API,
• Touch Events API,
• HTML5 date inputs (behind a flag),
• CSS transitions & animations for SVG (behind a flag), and
• CSS filters (behind a flag).

RemoteIE should be updated soon too.
