Our Old Exotics

Hello I'm Jordan Encee and I would like to ask about our favorite exotics and what will happen to them in year two. "Are we able to ascend or use Xür to upgrade all of our loved exotics from year one?" I ask this because I want to keep using Icebreaker, Gjallarhorn, and other exotics. Plus there be no reason why xbox fans will be getting the exclusive exotics if we can not use them for the full attack or defense stat. Can it be used for previous events in year one, yes, but we as the community will like to use these exotics against Oryx. Could there be good or even better exotics in The Taken King, sure, but that shouldn't mean it cost us our favorite exotics that we hold dear to us. I know nothing is confirmed or nothing has been said about what happens about this but ascend states "Increase the Attack/Defense value of this weapon/armor to the highest available in Year 1." So does that mean we can not use this anymore or are we getting something similar to ascend? I wanna thank you for reading this and also have a great day.
