The reason the listed date is 2016 is because Blizzard just reused the Overwatch 1 game ID in the MS store for Overwatch 2, it was basically them setting the price to free and submitting a new set of files to update to. Most likely because they wanted the smoothest of transitions from OW1 to OW2 and doing it any other way would have required directing users to a new store page and having them manually download it. Done the way they did, the user experience was the same as normally updating the game.
