This year, Xbox One players of Destiny haven't been able to get several items in Destiny due to PlayStation exclusivity. There isn't too much of huge worth, but the Monte Carlo and more specifically Hawkmoon have been pretty significant absentees due to the Sony preference of the game.
If you play on Xbox, there is unfortunately going to be more exclusive content in Year 2. This year, it seems only one Exotic weapon is making it across on PlayStation in the form of exotic scout rifle Jade Rabbit. There is also an exclusive Strike called Echo Chamber, a multiplayer map and a set of gear for each class exclusive to Sony.
