The Game of Thrones Geek Group discussion

I am obsessed with the tv show and currently reading the second book. Please no spoilers, but who do you think will win the game in the end? I think it may be Tyrion Lanister.

I'm hoping to see Tyrion on a dragon, even though their is no basis for this. I see Jon Snow or a Targarian, or maybe a new player? What the hell do I know thats not an answer. All of Westeros is probably going to collapse into its traditional kingdoms.

Jon Snow. I think he IS a Targaryen....

Maybe Arya along with Robert's bastard Gendry? Maybe someone that haven't been introduced yet?
