I think you didn't understand. He has two scenarios for an ending he thinks would be better.
That doesn't mean he has drawn it so it can be downloaded.
Basically I think he wrote here what his ideas are.
I think many people don't like the real ending so it's only natural that many think about a more fitting end. I have one myself, which is close to the original. So Light dies and the world goes back to normal. But in my ending he doesn't loose to Near and was able to kill them all (but was killed by Ryuuk after that).
@cooler: correct me if I'm wrong about the first part.
