Deadline is reporting that Paramount Pictures has hired Akiva Goldsman (A Beautiful Mind, Fringe, Insurgent, Angels & Demons, etc) to create a a cinematic universe road map for Transformers. The writer/producer would work with current Transformers executive producers Michael Bay, Steven Spielberg and Lorenzo di Bonaventura to determine a "potential multi-part Transformers sequel and come up with potential spinoff films based" on the franchise and then use multiple writers to hammer out the various scripts.
The approach is one already used by Marvel where the over all road map is controlled and maintained by Kevin Feige but the details of how each movie within that road map is executed is decided mostly by the writers and directors with the road map altered as better ideas dictate it. Basically sounds like Goldsman is being given the Feige role for Transformers but without any final word powers. Disney is also doing this with Star Wars but there currently isn't an official grand master controlling the vision there but for now JJ Abrams holds that non-official role.
It also seems Bay remains in play to direct the next film. According to the article the goal is to have "something hammered out when [Bay] completes production [on 13 Hours] so that the next Transformers pic can move forward quickly." That sounds like Bay is seriously considering helming Transformers 5 (can't blame him since each film nets him around $100 million plus). So whatever vision Goldsman comes up with will have to take that heavily into consideration.
My main recommendation is Goldsman should have a pow-wow with the IDW writers as they seemed to have nailed a natural approach to Transformers as individual characters while doing some rather outstanding world building, both of which have been rather significant problems with the previous movies and often been very difficult nut to crack for most Transformers writers regardless of format. It could be better (way to much hinting, not enough showing) but the world building of IDW's TF comics in the last five years have far outstripped the previous 25. To be in that team of writers and help develop the next trilogy and potential tie-in films.... One can dream.
