That is great news indeed!
Regarding the nudity, there was slightly more nudity than in the books, but it was well managed I think. Stating the differences that I can recall:
The "Tyrion at the brothel scene" wasn't in the books (and I do think a brothel in Winterfell doesn't fit quite well, I don't see the Starks allowing that kind of business in their walls), and in the first scene Daenerys appears, she wasn't suposed to be naked, and Viserys should have nipble-twisted her over the dress.
To balance this, they did not show Catelyn Stark naked, which was, I think, probably due to the age of the actress and/or to the possible and understandable modesty of the actress.
Also, at the Dothraki wedding, it shouldn't have occured mere dry humping, on the book it was real six that happened.
The rest of the scenes were all on the book, the final one, etc.
Just stating the differences, I think they did a great job!
