This one premiered at Anime Boston 2008, of which I was in attendance. Having never seen Gundam Seed Destiny, I thought this one would end with a very audible clunk for me, but it ended up almost bringing me to tears (me, a 20-year old guy!).

"The Final Goodbye" was entered in the Romance category, and why it didn't win, I dunno. Here's the link for all interested.
