Needless to say, the information has now been removed from his profile.
To quote: In it, he says he's "working in high security department for research and development involving strategic planning for medium and longterm projects."
He goes on to say his R&D projects include: "128-bit architecture compatibility with the Windows 8 kernel and Windows 9 project plan." He's also responsible for "forming relationships with major partners: Intel, AMD, HP and IBM.
A 128-bit version of Windows 8 would represent the next leap in performance. According to Microsoft's plans to release a new desktop version of Windows every three years, Windows 8 is scheduled to become available in 2012."
