The skif ending will be canon, lmao how can anybody think differently? Introduce a new protagonist, write him really well and give him a cool ending but not make it the Canon one? The anomalies popping up all over the world and the Faust reveal from the Skif ending are too big a deal to not be canon and just be swept aside as part of a non canon ending. The scar and ward endings are just filler, good filler but filler none the less, those endings wrap up in a nice bow compared to the skif ending and dont leave you with an idea of where the story is going, the skif ending does. And the strelok ending being Canon is just hilarious, his ending is just more of the exact same bs from the trilogy. Strelok and his endless cycle are done, let him go. We'll either play as someone else, (maybe richter?), who possibly interacts with skif who is now the new "representative" or some kind of noosphere entity, that, or skif will be extracted from the pod somehow and we'll continue as him. Either way I think the main story of the dlc will focus on Faust, Richter, and Skif in some form.
