Personally no I wouldn't say they are getting a raw deal. Bungie had listed fall of 2016 originally as a launch for Destiny 2, which would've been next gen only regardless. So frankly they said without saying that Destiny 1 would be dead for next generation by that time frame anyways. They just decided to squeeze another year out of Destiny 1 and eliminating old gen probably makes it easier for them to move seamlessly back into Destiny 2 development I'd imagine.
