Vista SP1 delayed until "before the end of February"

Looks like Microsoft have pushed back the release of Windows Vista service pack 1 until near the end of February - even though the service pack has been finalised. There will be 2 service packs. The 32 bit version is around 440Mb, while the x64 version clocks in at around 730Mb!

EDIT: Vista SP1 can now be downloaded directly from Microsoft.
