The very first YouTube comment more-or-less sums up my thoughts:

I’m watching this in the nude. & yes, I’m very excited :}

More to the point, though you don’t seem him in many frames, the trailer is clearly centered around Tyrion (who’s also, in my opinion, the lynchpin of the novel). Peter Dinklage has risen to great heights on the back of that small man, Tyrion Lannister, and it will be fun to watch him climb yet higher with his performance in the second season of Game of Thrones. Great stuff.
