I'm going out on a limb to make a prediction. This is really how I see it all unfolding:

Hillary will win Pennsylvania, but Obama will close the gap there enough to continue perceptions that Hillary simply can't come back enough to win. The next major event will be Obama winning North Carolina by a significant margin, which will solidify his lead. The rest of the primaries will still play out, but once all the voters have had their say, the superdelegates will predominantly choose to support Obama, wrapping up the nomination some time in June.

Unless Hillary wants to commit complete, unrecoverable political suicide, she will also voice support for Obama, which will go a long way towards stemming the threat of party defection we've been hearing about primarily from her supporters.

Once the Democratic support is largely unified behind Obama and the campaign focus shifts to Obama/McCain debates and such, the tide will turn in Obama's favor overall and ultimately, he will win the Presidency.

But like Cacophony, I've been wrong before. A lot. And much of this depends squarely on how Hillary behaves, so there is still a large measure of uncertainty involved.
