NEW SEASON RANKED ( Will Solo and Flex and 3vs3 continue to exist or not )

Its a dumb questions but i dont know in what board should i put it . Lets start with the fact that in season 9 we will have position ranks. SO my question is will we have position ranks for solo queue, different position ranked for flex and different for 3vs3 ( laner or jungler)? Or solo and flex will be united and become 1 queue? Then what will happent to 3vs3, will it function as we have it today?
