I found a website that translated a final document Satoshi Kon wrote for his fans and loved ones.

Satoshi Kon's last words | Makiko Itoh : Not a nameless cat.

I am rather sad about his passing but it was nice to learn he was able to sort out a few things before his death, so he was able to leave with little worry.

For those who don't know who he is, I still say you should read his final words, its not often people get a chance to write down their thoughts before passing and Satoshi wrote a rather moving if not personal farewell letter.
