If we look at the catalysts released since last season: SOTH: NTTE, the shotgun, Hawkmoon, and Leviathan's Breath. SOTC: Ticuu, DMT, Heir Apparent. If this is how they're going to do it, only one old weapon will be getting a catalyst at a time now, and since both of the old weapons were Y3 event/ quest weapons, I wouldn't be surprised if f'ing Bastion got one next season, partially because we're supposedly dealing with more time travel and going back to the corridors of time like we did to get Bastion 2 weeks early. Now assuming they haven't changed the catalyst like they did with Black Talon, Cerberus, and Trinity, Thorn is supposed to get +20 range and +30 stability.
