Bungie hasn't made any weapon specific announcements for the new Expansion Pass. I will say, that Bungie has mentioned in the last couple weeks that they are doing some serious exotic weapons tuning adjustments, and that's expected to be pushed out in an update before the expansion. I would keep checking the [url=http://www.bungie.net/en/News]Bungie Blog[/url] for all official information, directly from the source.
