Microsoft may have just taken the wrapping paper off of IE9, but the IE10 rumors are already starting to surface. The latest, and possibly first, IE10 rumor says that it will ship with Windows 8.
This information comes from Win7China, who also provided some of the first legitimate Windows 8 screenshots. Because they potentially have a solid source of information, this rumor holds a bit of weight. They also state that IE10 is already in Windows 8 M3, but we have yet to confirm that information.
The idea of including IE10 with Windows 8 seems logical. Considering that IE9 just launched, if the rumored Windows 8 launch days are correct, the browser would be well over a year old when Windows 8 finally ships to the consumer. Other than this little bit of information, not much else is known about IE10.
There have been a lot of leaks surrounding Windows 8 over the past few weeks. While we have yet to see the new dynamic interface in the new platform, "Aero Lite" has shown the general direction Microsoft is taking with the Windows 8 UI.
