What next?

Now that President Obama released his birth certificate, what will happen next with the "birthers" and Donald Trump?

1. The birthers will say "we were wrong" and go away?
2. They will claim it's a forgery (as they have with the previously disclosed short form)?
3. They will move on to different claims such as that he's still not a real American (having spent part of his childhood in Indonesia), his school records haven't been released, Arabs paid for his college education, etc?
4. Create a new conspiracy over why he didn't do this three years ago?

Personally, I'm guessing #1 will not be the response.
