Regarding the Tauntaun sleeping bag, that page now has some news on it:
"ATTN Tauntaun Fanatics! Due to an overwhelming tsunami of requests from YOU THE PEOPLE, we have decided to TRY and bring this to life. We have no clue if the suits at Lucasfilms will grant little ThinkGeek a license, nor do we know how much it would ultimately retail for. But if you are interested in ever owning one of these, click the link below and we'll try!"
The 'link below' they mention is to have them e-mail you if it ever becomes available. :)
