If you don't want to be spoiled for season 10 stop reading! Ok fair warning. Anyway who will you miss the most? For me it definetly will be May followed by Brock than Max.
EDIT: on an offial Japanese website Brock is scene with Ash and Hikari. Pics are on the main page. So now my order will be May than Max
