As an Xbox user I understand system exclusives and I don't harbor any ill will towards bungie over this. Having said that, I do feel a year is a bit extreme. Most timed system exclusives (cod for example) are a month or so, but it is what it is. Now if once the exclusivity expires Xbox users must pay an additional fee in order to gain access to this content that will bother me. But at this point there is no definitive information as to whether the exclusive content will cost any additional amount on Xbox so I am reserving judgment in that department.
