Thanks to Kev for the following.
If you find all but one of the golden lions in Wheelman and complete the game, when you go to the location of the last remaining lion, wherever that was, there will instead be a compass. The numbers on the compass are Hurley's numbers. Collect it and a message appears: "Locke will kill Jacob. Vin"
Considering that the game was release in March, that's an amazing early spoiler..? And the spoiler source, Vin Diesel, seems equally surprising...?
