News are coming that Microsoft Office 15 Milestone 2 (M2) build 15.0.2703.1000 has been leaked and available for download on various torrent websites.
Currently only 32-bit build has been leaked and works in Windows Vista and 7.
Since its a Milestone build, its quite buggy atm.

As usual we suggest you to stay away from these leaked builds and wait for official builds from Microsoft.

But I think Office 15.* is for Mac (Office 2011 for Mac).

@Ayush
Both Office 2010 for Windows and Office 2011 for Mac were developed as part of the same release "level", as I put it. So both are classified Office 14
Same as how Office 2007 and 2008 are both Office 12

.@Willie then what was office 13?!
Swapnil
Does it work with Windows XP???
If not, Microsoft is at it's own loss of money and market share.
I cannot test because I have Office 2010 installed. I don't want to uninstall my Office 2010 because I cracked it with many difficulties and 6 days of searching on the Internet.

Does it work with Windows XP?

MS ignore thats number

CONFIRMED,
This doesn't work on Windows XP. I downloaded Office 15 M2 via torrent and when I launched the EXE Setup file, it gave an error that it could not find something in the KERNEL32.dll file.

Microsoft, you can not even think of the result of not supporting Windows XP. Why spend time, money and effort when ONLY 50% OF THE WORLD CAN GET IT.
ACCORDING TO APRIL 2011 REPORT FROM NET APPLICATIONS, THE COMBINED MARKET SHARE OF WINDOWS VISTA AND WINDOWS 7 IS 35%.
EVEN IN THE FUTURE THIS COMBINED MARKET SHARE IS NOT EXPECTED TO GO ABOVE 48% ACCORDING TO MY EXPECTATION.
Microsoft, beware your loss is coming.

All what you said is true. I think they will even end the support for Microsoft Security Essentials for XP. I started to hate Windows and I already have a dual boot of Windows 7 and Linux Ubuntu. I even started to like Linux more than Windows.

What's the point of having Windows XP anyway? It's outdated and sooner or later will reach it's end of life (in 2014 I believe according to Microsoft) I suggest you update to Windows 7 or wait for Windows 8. Invest in newer technology.
