Hmm I guess in Baekhyun's tags he mentioned an exo fanmeeting, a solo concert and (a presumably solo) fanmeeting and in that order which could seemingl correspond to their order in the year. I think I personally would imagine Baekhyun or CBX's comeback being the first comeback I&B100 handling because I feel like they'd want to make a splash to increase confidence and those feel like the two safer comebacks to do that with. That being said, I hope they do some smaller things like OSTs or acting roles being announced first since otherwise the first thing I can think that they'd do would be Minseok's birthday. There's certainly a noticeable gap while we wait but maybe we'll get some more answers this week.
