Highly suspicious

I have been thinking for a while that why are the cvs bringing the two ex-leads of the story all of a sudden. Are they changing the plot or starting a new season. The cvs bringing the two ex-leads should realize that in the end one of the fandom is going to get hurt, they should have either one of the leads. We are shown mini stories which are half the time meaningless and swaron couple are going round and round in the same course they started in.
There have been ads of new serials are coming from the 25th and some shows are ending. What does that mean to d3.
I have strong doubt that the new creative team is going to start a all new season of d3 that is why they are getting the old characters.
