I don't think we'll be seeing DLC echoes. I feel like after E3 everyone thought echoes were gonna be a HUGE deal and they were gonna fill out the roster with them, but I feel like we were mistaken. I mean how many more did we get after E3? Richter Belmont, Chrom, Dark Samus, and Ken. Only four. So I don't think echoes were what we thought they were, as a way to fill out the roster, but rather Sakurai trying to get in a few more characters that were highly requested and made sense in Smash. To be honest I would rather see 1 unique character for DLC than 10 echoes. I'm not a huge fan of echoes because there's already so much overlap on the roster, with the three Links still being similar, Captain Falcon and Ganondorf essentially still sharing the same moves, Mario and Luigi still being far too similar... imo the last thing we need is more characters with the same moveset. I feel all the echoes that I was okay with are in the game, which was Richter, Chrom, and Ken as they do have a lot of similarities to the person their echoing.
