Microsoft will ship Internet Explorer 11 with Windows 8.1 later this year, but isn't saying whether the browser would also be available to Windows 7 users From Computerworld:

Microsoft has said little about IE11 -- it confirmed the browser only last week -- other than that it will be part of Windows 8.1, the free update to Windows 8 slated to launch as a preview June 26 and appear in final form some time this year.

"[IE11] is the only browser that is built for touch," Microsoft said in a May 30 blog post. "IE11 will offer even better touch performance, faster page load times and several other new features we think you will enjoy."
