From Christopher Isherwood: Getting Things Right (pp39-56)
by Thom Gunn (in Hiding in Plain Sight: Essays in Criticism and Autobiography)
In the last of these he goes on to present a hypothesis: “Just let us suppose, however...” What if George dies in his sleep? Again he disclaims responsibility; we are free to “suppose” that George does or George doesn’t, but since the hypothesis (like the analogy earlier) has been suggested, it is there on the page, and brings home to us with all the more force that it be not now, yet it will come.
The death is described in the original scientific tone:
Throttled out of its oxygen, the heart clenches and stops. The lungs go dead, their power line cut. All over the body, the arteries contract.
Bit by bit we watch the body close down.
And if some part of the nonentity we called George has indeed been absent at this moment of terminal shock, away out there on the deep waters, then it will return to find itself homeless. For it can associate no longer with what lies here, unsnoring, on the bed. This is now cousin to the garbage in the container on the back porch. Both will have to be carried away and disposed of, before too long.
These are the last words of the book, fierce, factual, and yet speculative.

I just happened to have this around and there is an entire school of thought supporting the idea that George does not die. Just sayin'... Anyway, Tom Ford himself made the comment that he needed to take the ambiguity out of the ending. When I have a bit more time, I could go find that interview.
(When I first read it, I thought he died as well...still do.)
