I think the chances of Twice getting above 1 million next comeback is extremely high, maybe 85-90% likelihood.
So on Itzys last comeback they were able to get 335k in sales. Similarly Aespa got 519K last comeback. Twice however got 700k in the first month.
As you know Itzy has now confirmed 720K in their first month nearly double their last comeback. Aespa did an amazing 1.6 million triple their last comeback. If we assume Twice does double they will sit at 1.4 at least. If we assume they do a little better than double 1.6 million is possible. If they triple their numbers 2.1 million is possible. So heres what I think.
Low Estimate: 1-1.2 million
Mid estimate: 1.2-1.5 million (Most Likely)
High Estimate: 1.5-2.1 million (least likely”
What do you think?
