Update February 28: Another top Microsoft beat writer is chorusing April 8 for the Windows 8.1 Update 1 release.
SuperSite for Windows' Paul Thurrott posted a tweet February 27 that read: "Windows 8.1 Update 1 will hit MSDN on April 2, Windows Update on April 8."
So according to Thurrott, MSDN subscribers will get the first crack at the update, followed by a general public release several days later.
April 8 is a Patch Tuesday, so expecting an update sent through the wires requires no far stretch of the imagination. We'll just have to wait and see if these rumors come to pass.

Screenshots of a Windows 8.1 Update 1 pre-release build made it online earlier this week, showing a tweaked design to make the OS more welcoming to mouse and keyboard users.
