I would rather see new minifigs introduced than another Cho it would be cool for them to introduce other characters like Lee Jordan to the mix instead of having two Cho's this year.
Something about this wave that bugged me was the Harry we got in the Gwarp set they used a common torso that has appeared in 15 sets since 2016 despite them making the accurate torso in the new collectible minifig series.
KingNono who is the main leaked of this wave has stated that minifigure lovers will love this D2C as well as other licenced D2C's such as the lego death star which cost £410 had 26 minfigures included in the set.
Its rumored to be a £400 set it will probally have leaky cauldren in it the 2010 set had 3 building and was £133 so this one will likely have 6-7 building.
