Who Leaked Windows 7?

BitTorrent brought the Christmas present Santa didn't: Leaked build of Windows 7, whose official Beta 1 release is perhaps days away. Was this a craftily timed Microsoft marketing leak?

I sure as hell think so. It's certainly what I would do if I worked at Microsoft on Windows evangelism. The timing is perfect, from a marketing perspective. The leaked build hit BitTorrent sometime on Saturday, right after Christmas when the Windows geeks had nothing better to do and bloggers and journalists had nothing better to write about. The leaked build is designated "7000," which strongly suggests that the code is the same as forthcoming Beta 1, or close to it.
