To answer huynhd's question (or rather add to your comments), the Cipher no longer drops at all; you have a chance from getting those exotic weapons from the chest now. Also, you're guaranteed an exotic the first time you open the Prison chest. I'm also going to assume (but I could be wrong!) that Xur is going to start selling the bounty weapons (the ones moving forward to Year 2, that is) once TTK drops. Comments I've read in Bungie's armory makes it sound that way, at least.
Thank you! <3
