Microsoft is working steadily to bring up the Service pack release and according to Wzor, they made around 35 builds between January 11 and March 2. The builds 7601.16517.100301-1718 and 7601.16518.100302-1530 have been already produced by Microsoft but it would not make any sense leaking this release until it atleast reaches Beta development.

Meaning behind the Windows 7 build numbers, say 7601.16518.100302-1530, 7601 represents the major build number, 16518 the minor version, and 100302-1530 the date and time at which the release was compiled, namely March 2, 2010 at 15:30. Wzor expects this release and available for download in Mid April of 2010.
