Remember when this forum raged about Animated and then looked silly afterwards?
Good times.
They may be writing something or other , but their main job will be executive producing. Besides, without the influence of Michael Bay, they wrote the critically acclaimed Star Trek.
Well, the WFC Exodus book is based on Hasbro's own Transformers "bible", which serves as backstory for Prime and presumably future Transformers series. The game doesn't fit in too well into this, but there you go, it's just a game with a bare minimum of storyline and characterisation.
From Hasbro's perspective, Exodus/their bible is the pre-Earth storyline for this new franchise, with the game being the mass market media to represent it.
As for whatever High Moon Studios and Activision think - they say what is needed to sell the game to the millions of people who aren't really Transformers fans (in the sense that you and me are fans) but remember "the cartoon from the 80s". So they've said a load of rubbish in videos, podcasts and interviews about it being the prequel to the Sunbow cartoon, which is of course, totally untrue.
I think you people are taking that a little too literally.
The way I read human drama is a marketing buzzword for "more complex and developed stories/characterisation" or something to that effect. Saying "more robot drama than ever before!" doesn't make any sense.
