Dig around in the history of transformers toys

By accident I was in a local bookstore the other day and remember that someone asked who created the seacons in the cartoon well this book had the story plans for season three of t.v. series and going into headmaster,masterforce and victory. So apparentily the story for t.v. series and toys was supposed to go like this: The Quintessons were supposed to have created:
1. The predacons
2. the plans for trypticon which were carried out by the construticons.
3. The Terrorcons (that is why they were showed with quintessons during season three)
4. The seacons.
But when they decided to stop making transformers around the time of the begining of season three the quintessons story arc in the series and the toys was canceled.
