As you know part of the scope for 3.3 was a revised admin bar that would reduce duplication in the admin header. The first draft of it has been posted to Trac.
It needs a color refresh, some optimization, some decisions about which links going where, etc, but is the starting point we are using. Would like to get it back toward the lighter gray we used in the header before, but with some border maybe so it doesn’t look like browser chrome. Fiddling with the links and stuff will happen on Trac, but if anyone wants to mock up some color variations, we have until Sunday.
