. I think he is cute, but never thought OMG... I left the movie thinking OMG he is HOT! Not sure what it was but whatever it was, it worked well for him 
I thought it was just me
I wanted to bump this because people are still asking about the end scene and this thread was getting lost on page 2!
I also wanted to add that I think the point of the scene was to show that, unlike Calypso, Elizabeth showed up for that day and because of that, unlike Davey Jones, Will will now continue his job of transporting the dead to the other side.
At the end of the movie, my friend and I were totally slack-jawed at how AMAZING he looked. I'm pretty sure the only words I was able to utter were, "Uh. Muh. Gawww." 
I've seen interviews with both OB and KK and they have said that they are pretty much done with the pirate movies. I think that IF they decide to go on with a fourth sometime in the near future, it will be following Jack's story and they will leave Will and Elizabeth's as it ended in this one.
Will's job is done Nikki!
From Wikipedia:
After the credits, in a scene captioned "Ten Years Later," a young boy approximately ten years of age is seen singing "A Pirates Life for Me" as Elizabeth walks behind him. It is implied that this is the child of Will and Elizabeth. The sun sets followed by a green flash and Will, on the mast of The Dutchman, sails towards the shore. According to the film's writers, the curse of The Dutchman is broken if, after the ten years, the captain's lover reamains faithful. The final post-credit scene suggests that Will can now return to land, as Elizabeth has remained faithful. The green flash, which symbolises a soul returning from the dead, supports this theory. Apparently, a scene of dialogue between Tia Dalma/Calypso and Davy Jones, which explained this, was cut from the film, leading to confusion about the ending.
