I think it's likely that those who haven't endorsed will be hanging back and seeing how things go. So if Obama cleans up March 4th -- I think that will unleash a flood. If it looks like it's all but technically over, people will want to push it all the way ASAP so the party can unite against McCain and get to winning the general election.
If, however, Hillary Clinton does very well or even if she barely wins one of the big states, I'm not sure. I think they'd mostly wait, though some superdelegates from the states that vote March 4th might go one way or another when they see how their constituents voted (I'm thinking about how Feingold endorsed Obama after Obama decisively won the WI primary, for example).
I agree with Finn that an Obama-Clinton or Clinton-Obama ticket is extremely unlikely (I have a bet with blatham to that effect, made quite a while ago). I did just have a thought, though. I could imagine a pro forma offer -- that both parties agree to, and the conclusion, ahead of time -- if Obama gets the nomination. As in, he'd make the offer, she'd say no. This gets him credit for making the offer, allows her to exit with some dignity, and sets her up for a future run if she puts her declination in terms of how she is interested in the presidency and only the presidency (and will stay in the Senate until then).
Just a thought, I don't really think it'd happen though.
Re: the Messiah stuff -- I've now been to two Obama rallies personally and have read the text of countless speeches. A strong, recurrent theme is "it's not about me, it's about you." Expressed another way, "Change doesn't happen from the top down, it happens from the bottom up." He regularly challenges his audiences to do something, themselves -- the $4,000 tuition credit for college students is earned through community service, for example.
Andrew Sullivan had an interesting take on "We are the ones we have been waiting for...."
Andrew Sullivan wrote:"We Are The Ones We Have Been Waiting For"

It surprises me that some commentators see messianism in a phrase that strikes me as deeply anti-messianic. The line is akin to "there's no Justice, there's just us" in that it calls on us to give up our fantasies of some deus ex machina descending to make everything right and just, and urges us to roll up our sleeves and get involved.
In a slightly different context, Reagan could have said it. As someone involved in the gay rights world for a while, it strikes me that this is also a core message we need to convey. The Clinton model - exemplified by the Human Rights Campaign - is: give us some big donor checks, we'll hire a lobbyist (if you're lucky), and we'll work the Democratic party establishment to give you your equality (which somehow never happens). Meanwhile: keep whining (and sending the checks). The Obama model is: you will only get your equality if you stand up for it, risk your job, status, even life for the sake of your own integrity. Stop whining and start explaining and persuading and acting.
So many gay people over the years have asked me where our "leader" is. It's the wrong question. We are the ones we have been waiting for. Be the change you want to see in the world. And the world changes. In exact proportion to the number of gay people who have abandoned their fear and self-hatred, it already has. No excuses, guys. And no need to wait.
