What about Fiji?
Perhaps, that will be a SP1 or SP2 for Vista.

Windows "Fiji" is rumored to be Microsoft's present codename for either an
update to or a successor of Windows Vista, Microsoft's upcoming operating
system. Microsoft has not acknowledged this release, or any of its
features.

Will the delay in Microsoft's Windows Vista have a domino effect on other
planned releases of Windows?
Partner sources close to the company said that Microsoft has sketched out
plans for Windows "Fiji" (also referred to by some Microsoft watchers as
Vista R2)—the version of Windows set to follow Vista—as for Windows
"Vienna," the successor to Fiji, partner sources close to the company
said.
Microsoft has not shared broadly its working feature set for Fiji,
according to partners contacted by Microsoft Watch.
Nor have company executives talked about what's on tap for Vienna, the
version of Windows formerly code-named Blackcomb.
And exactly when either Fiji or Vienna will hit is anyone's guess.
Since Microsoft announced at the end of March that Vista was running
behind schedule and would not be ready to launch in time for the 2006
holiday season, Microsoft brass have gone mum about its future plans for
its desktop and server Windows releases.

The code name "Blackcomb" was originally assigned to a version of Windows
that was planned to follow Windows XP (codenamed "Whistler"; both named
after the Whistler-Blackcomb resort) in both client and server versions.
However, in August 2001, the release of Blackcomb was pushed back several
years and Vista (originally codenamed "Longhorn" after a bar in the
Whistler-Blackcomb resort) was announced as a release between XP and
Blackcomb. Since then, the status of Blackcomb has undergone many
alterations and PR manipulations, ranging from Blackcomb being scrapped
entirely, to becoming a server-only release. As of 2006, it is still
planned as both a client and server release with a current release
estimate of anytime between 2009-2012, although no firm release date or
target has yet been publicized.
In January 2006, Blackcomb was renamed to "Vienna",[1] and in April 2006,
Windows "Fiji" emerged as a codename for an interim release between Vista
and "Vienna".
Colin Barnhorst said:
RC1 is a stage. The first builds are not the ones released to testers
outside of MS. The first RC1 build you will see will merely be the one
that passed standards for release to outside testing.
RC1 will evolve through a hundred or more builds while the rtm branch is
being built with successive builds until it meets the standards for
release as Vista final.
Several of the RC1 interim builds will be released to outside testing,
like the TechBeta program and the TAP's. All this time the successive
builds (new builds are made overnight) will be in use by folks inside MS.
Through all of this the teams at MS are going head to head over inclusion
and exclusion of features and making judgments about projects at to
whether resources will permit meeting standards in time for release. If
not, such projects will be deferred until Vienna. Some work on Vienna is
already under way.
