Holmes cannot prove it, but he surmises that Moriarty or his associates did it in the short story 'The Final Problem.'
In the trailer, it shows a casket being lowered into a grave marked Sherlock Holmes: 18 something something to 1888. So it's safe to assume that he truly does die. But they could also do with this what Conan Doyle did after The Final Problem.
According to Sherlock himself, Colonel Sebastian Moran saw him at the falls, and Sherlock told his brother Mycroft later.
