Yesterday, Microsoft announced the new version of their web browser, Internet Explorer 9. But already, there are rumours of the next iteration being under development.

It is expected that just as Internet Explorer 9 debuted on MIX 10, Internet Explorer 10 would be demoed to the public in MIX 11 with a possible release date that coincides with the 2012 estimated RTM of Windows 8.

A post on Win7China also confirms the appearance of an IE10 version integrated with a recent Windows 8 M3 build. Although IE 10 was not spotted in the earlier builds of Windows 8 M3, Win7China has been credited with recent legitimate leaks of Windows 8 screenshots.
