I absolutely agree. Landa's fate so fitting, as getting killed off would have been too good for him. Everyone will know what he had done and will forever be marked for it; what side will have him, and where could he go after that? He'll get that bit of land he wanted, but Landa will be driven into isolation and I imagine his life will be threatened regularly. There are just many possibilities of all of the wonderfully awful things that will happen to him.
Quick edit, but I have to mention that I enjoyed the fact we don't see the actual carving of a swastika until the end, with Landa.

Daniel mentioned in an interview - that as strange he knew it sounded - they had the best Goebbels. I've never had an easy time even thinking of WWII, as it sends me into an angry tizzy, but I have become intrigued by Goebbels because he was so aware. I spent an evening at work recently photocopying Goebbels out of a German publication we have at work from 1936: Die Woche. I couldn't believe what I was seeing with all of these ridiculous advertisements for cologne and shampoo to make your hair blonder and cross-word puzzles that form swastikas; but the crown jewel of them all is a photo of Goebbels and Hitler at some formal function, both in nearly matching tweed suits. Hitler appears dour, but Goebbels had the largest smile I've ever scene on a person; it's unsettling yet completely amusing.
