I'm so happy to hear! My favourite of the new bunch is Kiriko (actually- my new main as well! Love her to bits ahahaha) so I'm thrilled to hear she'll be added!
As for replaying, currently I'm mainly waiting for the Sombra-D.Va storyline to wrap up and for the Widow storyline to finish (even though I'm aware- it's probably going to be a whiiiiile), and for the alleged Tracer route remake I heard was planned!
Again, absolutely stellar job on this game, I can't wait to replay it and I already know I'll have so many good words to review it with when I do!
